Some toddlers drink more milk than the recommended number of servings. This "milk diet" can lead to iron deficiency. A small group of these children also experience protein loss from the digestive system or gut. Iron deficiency can lead to anemia (low red blood cell count) and protein loss leads to hypoalbuminemia (low levels of albumin in the blood). Treatment usually requires limiting milk intake, offering iron rich solid food, and in children with moderate to severe anemia, iron supplements.</p> <h2>Key points</h2><ul><li>Too much milk can lead to iron deficiency anemia and protein loss from the gut.</li><li>Milk intake should be limited to a maximum of 500 mL (2 cups or 16 oz.) per day for toddlers and young children.</li><li>The main treatment for iron deficiency and protein loss from the gut due to excess milk intake is to reduce the amount of milk your child drinks and to increase the amount iron rich foods in their diet. For moderate to severe anemia, iron supplements are also needed.</li><li>See a doctor if your child drinks a lot of milk and is tired, weak, pale or has a swollen face, legs and feet.</li> </ul> <h2>Signs and symptoms of iron deficiency anemia and protein losing enteropathy</h2><p>Symptoms of anemia depend upon its severity, how fast the drop in levels of haemoglobin occurred and its cause. It also depends on how well a child’s body adapts to a low level of haemoglobin.</p><p>Symptoms of anemia include:</p><ul><li>pale skin</li><li>lack of energy</li><li>shortness of breath after exercise or play</li></ul><p>Protein losing enteropathy and hypoalbuminemia causes the blood vessels to leak fluid into surrounding tissue.<br></p><p>Symptoms of protein losing enteropathy and hypoalbuminemia include:</p><ul><li>progressive swelling of the feet, legs and face</li><li>muscle cramps or weakness</li><li>extra fluid around the lungs (pleural effusion)</li><li>swelling of the abdomen (ascites)</li></ul> <h2>Risk factors and prevalence of iron deficiency anemia</h2><p>Iron deficiency anemia is the most common type of anemia.</p><p>Around the world, iron deficiency anemia affects approximately 750 million children. In Canada, it is seen in 3.5% to 10.5% of the general population. Children have a greater risk of iron deficiency anemia due to their rapid growth, particularly in the first two years of life.</p><p>Children who are most at risk of developing iron deficiency anemia are those who are fed only breast milk or non-iron fortified cow’s milk formulas after six months of age, and those who drink an excess of cow’s milk. Children who are given cow’s milk before 12 months may also be at increased risk of developing iron deficiency anemia because their gut may not be ready to digest cow’s milk yet.</p> <h2>Diagnosis of anemia and protein losing enteropathy</h2><h3>Iron deficiency anemia</h3><p>Iron deficiency anemia can be diagnosed by your child’s doctor. They will do a physical exam and ask about your child’s energy levels, general health, diet and family history.</p><p>A blood test, called a complete blood cell count (CBC), can make the diagnosis of anemia by measuring haemoglobin levels. When the anemia is caused by iron deficiency, the red blood cells will also look smaller and lighter in colour when seen under a microscope.</p><p>A ferritin test may also be done. Ferritin is a protein found in the body that stores iron. A low ferritin level can indicate iron-deficiency.</p><p>Additional useful tests that measure the body’s iron are called iron studies.</p><h3>Protein losing enteropathy</h3><p>Protein losing enteropathy and hypoalbuminemia are suspected in children with swelling and low albumin levels in the blood. Your child’s doctor will examine them for swelling of the legs, feet and face. They will also examine your child’s heart, lungs and abdomen for extra fluid.</p><p>A blood test is often done to check the blood albumin level. A urine test may also be done to make sure there is no protein loss from the kidneys. When the cause of low albumin is not clear, further tests may be done including stool tests. One of the stool tests that may be performed is a 24-hour collection of stool to check for a protein called alpha-1-antitrypsin. By comparing the amount of this protein in the stool to the amount in the blood, doctors can tell whether there is protein loss through the gut.</p> <h2>Treatment of iron deficiency</h2><h3>Diet</h3><p>Limiting milk intake to a maximum of 16 ounces per day is usually the only treatment needed. The iron levels will gradually rise and protein loss from the gut will decrease.</p><p>Iron rich foods can also help to treat iron deficiency. Many iron rich foods, such as meat and meat alternatives, are also high in protein. Offer your child foods such as meat and meat alternatives, and iron-fortified cereals a few times each day. From one year of age, young children should begin to have a regular schedule of meals and snacks. In general, you may follow the advice in <a href="https://food-guide.canada.ca/en/">Canada’s Food Guide</a>.</p><p>Limiting milk does not mean stopping it completely. It is known that milk is a good source of calcium, vitamin A and vitamin D. From one to two years of age, children should drink 250 to 500 mL (1–2 cups or 8–16 oz.) of homogenized (3.25% M.F.) cow’s milk per day. They should not drink more than 500 mL (2 cups or 16 oz.) per day.</p> <h3>Iron supplement</h3><p>Your child’s doctor might also prescribe iron supplements. After a few weeks, values such as the haemoglobin level generally start to improve. Treatment is usually continued for at least three months to fully replenish iron stores in the body.</p><p>Iron supplementation can cause an upset stomach. Your doctor might divide the dose in half and ask you to give it two times per day instead of as one large daily dose.</p><p>Dairy products (milk, cheese, yogurt) can have a negative effect on the absorption of iron. Try to give iron supplements two hours before or after eating or drinking any dairy products.</p><p>Vitamin C can help iron absorption from foods. Oranges and other citrus fruit are good sources of vitamin C. Be careful with offering too much juice, as it is high in sugar.</p><p>Protein losing enteropathy and hypoalbuminemia caused by too much milk gets better fairly quickly when the milk intake is limited to an appropriate amount.</p><h2>Complications of anemia and hypoalbuminemia</h2><p>Untreated anemia in children can have serious effects on a child’s growth. Untreated anemia can affect intellectual ability and overall development. This can lead to problems with attention, reading ability and school performance. In rare cases, extreme anemia can cause a stroke.</p><p>Hypoalbuminemia can also have serious effects on a child’s growth. Excess fluid around the lungs can cause problems with breathing. In rare cases, excess fluid can build up around the heart making it harder for the heart to pump. Protein loss in the gut can also cause a loss of the proteins needed to fight infection and prevent clots, putting children at risk of severe infections or blood clots.</p> <h2>​Virtual care services for children<br></h2><p>Boomerang Health was opened by SickKids to provide communities in Ontario with greater access to community-based services for children and adolescents.

Anémie ferriprive et entéropathie protéinique liées à une consommation excessive de laitAAnémie ferriprive et entéropathie protéinique liées à une consommation excessive de laitIron deficiency anemia and protein-losing enteropathy related to excessive milk intakeFrenchNutritionChild (0-12 years)NANAConditions and diseasesAdult (19+) CaregiversNA2019-01-16T05:00:00ZHealth (A-Z) - ConditionsHealth A-Z<p>Le lait fait habituellement partie d’une alimentation saine et équilibrée. Toutefois, boire une quantité excessive de lait peut réduire le taux de fer dans le sang. Certains enfants peuvent alors perdre des protéines depuis l’intestin.</p><h2>Apport excessif de lait</h2><p>La quantité recommandée de lait de vache pour les tout-petits est de 250 à 500 mL (1 à 2 tasses) par jour. Certains tout-petits dépassent le nombre de portions de lait recommandé. Ce « régime lacté » peut entraîner une carence en fer. Parmi eux, certains souffrent aussi d’une perte de protéines depuis le système digestif ou intestinal. Une carence en fer peut causer une anémie (faible taux de globules rouges) alors qu’une perte de protéines entraîne une hypoalbuminémie (faible taux d’albumine dans le sang). Le traitement exige habituellement de limiter l’apport de lait, d’offrir des aliments solides enrichis de fer et, chez les enfants atteints d’anémie modérée à grave, de leur administrer des suppléments de fer.</p><h2>À retenir</h2><ul><li>Un apport excessif de lait peut entraîner une anémie ferriprive et une perte de protéines depuis l’intestin.</li><li>La consommation de lait devrait se limiter à un maximum de 500 mL (2 tasses) par jour pour les tout-petits et les jeunes enfants.</li><li>Le traitement principal de la carence en fer et de la perte de protéines depuis l’intestin causées par une consommation excessive de lait consiste à réduire la quantité de lait donnée à votre enfant et à augmenter la quantité d’aliments riches en fer dans son alimentation. Pour une anémie modérée à sévère, des suppléments de fer sont également requis.</li><li>Consultez un médecin si votre enfant boit beaucoup de lait, qu’il est fatigué, faible ou pâle ou qu’il a le visage, les jambes et les pieds gonflés.</li></ul><h2>Symptômes d’anémie ferriprive et d’entéropathie protéique</h2><p>Les symptômes de l’anémie ferriprive dépendent de sa gravité, de la rapidité de la chute du taux d’hémoglobine et de sa cause. Ils dépendent également du degré d’adaptation de l’organisme de l’enfant à une faible teneur en hémoglobine.</p><p>Les symptômes de l’anémie ferriprive sont principalement :</p><ul><li>un état de pâleur;</li><li>un manque d’énergie;</li><li>un essoufflement après l’exercice ou le jeu.</li></ul><p>L’entéropathie protéique et l’hypoalbuminémie entraînent une fuite de liquide depuis les vaisseaux sanguins vers les tissus environnants.</p><p>Les symptômes d’entéropathie protéique et d’hypoalbuminémie sont principalement :</p><ul><li>l’enflure progressive des pieds, des jambes et du visage;</li><li>des crampes ou une faiblesse musculaires;</li><li>une accumulation de liquide autour des poumons (épanchement pleural);</li><li>l’enflure de l’abdomen (ascite).<br></li></ul><h2>Cause de l’anémie ferriprive et de l’entéropathie protéique</h2><h3>Anémie ferriprive</h3><p>L’anémie ferriprive due à un apport excessif de lait est causée par trois facteurs.</p><ul><li> <strong>Carence en fer</strong> : Le lait contient une quantité très faible de fer. De plus, si un enfant boit une quantité excessive de lait, il aura l’estomac trop plein pour manger des quantités suffisantes d’aliments riches en fer.</li><li> <strong>Mauvaise absorption du fer</strong> : Le lait et les autres produits laitiers peuvent nuire à la capacité de l’intestin d’absorber le fer provenant d’autres sources, comme la viande et ses substituts et les légumes vert foncé.</li><li> <strong>Saignement microscopique</strong> : Boire trop de lait peut endommager la paroi de l’intestin (entéropathie aux protéines du lait). Cette affection provoque des saignements microscopiques pratiquement invisibles dans l’intestin. Tout type de saignement dans le corps entraîne une perte de fer. Avec le temps, ces saignements peuvent diminuer très fortement le taux d’hémoglobine, contribuant à l’anémie ferriprive.</li></ul><h3>Entéropathie protéique</h3><p>On ne comprend pas tout à fait comment la consommation de lait entraîne une perte de protéines depuis l’intestin. Une théorie suggère l’intervention d’un processus appelé atrophie villositaire. L’intestin grêle présente sur ses parois des projections en forme de doigts appelées villosités. Elles jouent un rôle important dans l’absorption des nutriments. On croit qu’un apport excessif de lait de vache peut réduire la taille des villosités (atrophie villositaire) et entraîner une mauvaise absorption des nutriments. L’atrophie villositaire rend les parois intestinales perméables, ce qui laisse les protéines s’échapper.</p><h2>Diagnostic de l’anémie ferriprive et de l’entéropathie protéique</h2><h3>Anémie ferriprive</h3><p>L’anémie ferriprive peut être diagnostiquée par le médecin. Il fera un examen physique de votre enfant et s’enquerra de son niveau d’énergie, de son état de santé général, de son alimentation et de ses antécédents familiaux.</p><p>Une analyse sanguine, appelée formule sanguine complète, permet de diagnostiquer l’anémie ferriprive en mesurant le taux d’hémoglobine. Lorsque l’anémie ferriprive est causée par une carence en fer, les globules rouges paraîtront également plus petits et plus pâles au microscope.</p><p>Une analyse de la ferritine peut également être effectuée. La ferritine est une protéine présente dans l’organisme qui stocke le fer. Un faible taux de ferritine peut indiquer une carence en fer.</p><p>D’autres analyses utiles, appelées études sur le fer, peuvent mesurer le fer présent dans l’organisme.</p><h3>Entéropathie protéique</h3><p>On soupçonne la présence d’une entéropathie protéique et d’une hypoalbuminémie chez les enfants présentant de l’enflure et un faible taux d’albumine dans le sang. Le médecin examinera votre enfant pour déceler toute enflure des jambes, des pieds et du visage. Il examinera aussi son cœur et ses poumons, et son abdomen pour déceler toute accumulation de liquide.</p><p>Une analyse sanguine est habituellement effectuée pour vérifier le taux d’albumine dans le sang. Une analyse d’urine peut également être faite pour s’assurer qu’aucune perte de protéines ne se produit au niveau des reins. Lorsque la cause de la faible teneur en albumine est incertaine, d’autres analyses peuvent être effectuées, dont une analyse des selles. L’une d’elles peut consister en un prélèvement d’échantillons de selles sur 24 heures pour vérifier la présence d’une protéine appelée alpha-1-antitrypsine. En comparant la quantité de cette protéine dans les selles à la quantité présente dans le sang, le médecin peut déterminer s’il y a perte de protéines depuis l’intestin.</p><h2>Traitement de la carence en fer</h2><h3>Alimentation</h3><p>Habituellement le seul traitement nécessaire est de limiter la consommation de lait à une quantité maximale de 500 mL par jour. Le taux de fer augmentera graduellement pendant que la perte de protéines depuis l’intestin diminuera.</p><p>Les aliments enrichis de fer peuvent également aider à traiter une carence en fer. De nombreux aliments riches en fer, comme la viande et ses substituts, sont également riches en protéines. Offrez à votre enfant des aliments comme la viande ou ses substituts ainsi que des céréales enrichies de fer à quelques reprises chaque jour. Dès l’âge d’un an, les jeunes enfants devraient commencer à respecter un horaire régulier pour les repas et les collations. En général, vous pouvez suivre les conseils du <a href="https://guide-alimentaire.canada.ca/fr/">Guide alimentaire canadien</a>.</p><p>Limiter la consommation de lait ne signifie pas de l’interrompre complètement. On sait que le lait est une bonne source de calcium, de vitamine A et de vitamine D. Dès l’âge d’un à deux ans, les enfants devraient boire de 250 à 500 mL (1 à 2 tasses) de lait de vache homogénéisé (3,25 % M.G.) par jour. Ils ne devraient pas en boire plus de 500 mL (2 tasses) par jour.</p><h3>Supplément de fer</h3><p>Le médecin de votre enfant peut également prescrire des suppléments de fer. Après quelques semaines, certaines valeurs comme la teneur en hémoglobine commencent généralement à augmenter. Le traitement s’échelonne habituellement sur au moins trois mois pour reconstituer complètement les réserves de fer de l’organisme.</p><p>La supplémentation en fer peut toutefois causer des maux d’estomac. Votre médecin pourrait alors diviser la dose en deux et vous demander de l’administrer deux fois par jour au lieu d’une seule.</p><p>Les produits laitiers (lait, fromage, yogourt) peuvent avoir un effet indésirable sur l’absorption du fer. Vous pourriez alors donner des suppléments de fer deux heures avant ou deux heures après la consommation des produits laitiers.</p><p>La vitamine C peut aussi faciliter l’absorption du fer contenu dans les aliments. Les oranges et autres agrumes sont de bonnes sources de vitamine C. Prenez garde de ne pas donner une quantité excessive de jus, car cet aliment est riche en sucre.</p><p>L’entéropathie protéique et l’hypoalbuminémie causées par un apport excessif de lait s’estompent assez rapidement lorsque l’apport est limité à la quantité appropriée.</p><h2>Complications de l’anémie protéique et de l’hypoalbuminémie</h2><p>L’anémie protéique non traitée chez les enfants peut entraîner de graves conséquences sur leur croissance. L’anémie protéique non traitée peut détériorer leurs capacités intellectuelles et leur développement général. Des problèmes d’attention, de capacité de lecture et de rendement scolaire pourraient en résulter. Dans de rares cas, une anémie protéique extrême peut causer un AVC.</p><p>L’hypoalbuminémie peut également produire de graves effets sur la croissance de l’enfant. Une accumulation excessive de liquide autour des poumons peut causer des problèmes respiratoires. Dans de rares cas, l’excès de liquide peut s’accumuler autour du cœur, ce qui diminue sa capacité à pomper. La perte de protéines depuis l’intestin peut également entraîner une perte des protéines nécessaires pour combattre les infections et pour prévenir la formation de caillots, exposant les enfants à des infections graves ou à l’apparition de caillots sanguins.</p>

However, drinking too much milk can lead to low levels of iron in the blood and some children can then lose protein from the gut.<br></p><h2>Excessive milk intake</h2><p>The recommended amount of cow’s milk for toddlers is 250 to 500 mL (1–2 cups or 8–16 oz.) per day. Some toddlers drink more milk than the recommended number of servings. This "milk diet" can lead to iron deficiency.

Iron deficiency can lead to anemia (low red blood cell count) and protein loss leads to hypoalbuminemia (low levels of albumin in the blood). Treatment usually requires limiting milk intake, offering iron rich solid food, and in children with moderate to severe anemia, iron supplements.</p> <p>Breast milk or formula is a good source of iron for the first six months of life. Iron stores in babies naturally decrease by four to six months of age. After six months, the amount of iron in breast milk is not enough, and solid foods are usually introduced.</p><p>When introducing solid foods, infants should start with meat or meat alternatives, in order to get enough iron and protein in their diet. Meat alternatives include fish, egg yolk, tofu, lentils and cheese. Iron-fortified cereals are also a good source of iron that can be started at four to six months of age. Breast milk and/or formula should continue until nine to 12 months of age, when homogenized (3.25%) cow’s milk may be started to complement solid food.</p><h3>Iron deficiency anemia</h3><p>Iron is an important mineral that we get from our diet that is needed to make haemoglobin. Haemoglobin is a protein in red blood cells that allows the cells to carry oxygen to the tissues in our body. Anemia occurs when you have low levels of haemoglobin in your body. When the anemia is caused by not having enough iron this is called iron deficiency anemia.</p><p>When a child has anemia, they are not getting enough oxygen delivered to the tissues in their body. This can cause them to look pale and tired, and cause weakness.</p><h3>Protein losing enteropathy</h3> <p>Drinking too much milk can also cause protein loss from the gut (protein losing enteropathy).</p><p>Children with protein losing enteropathy have severe protein loss through the gut and this results in low protein levels in the blood.</p><p>The main protein found in the blood is called albumin. Having low levels of the protein albumin in the blood (hypoalbuminemia) can cause the blood vessels to leak fluid into the tissue. Extra fluid in the tissue can cause swelling (edema) of the legs, back and face. Hypoalbuminemia also puts you at risk for infections.</p><p>Hypoalbuminemia and edema can be caused by other disorders. Your child’s doctor will ask questions about your child’s overall health, symptoms of diarrhea or blood in the stool, and family history of gut, liver, kidney or heart diseases.</p><p>If there are no other causes for protein loss, it is possible that too much milk is the cause.</p><h2>Key points</h2><ul><li>Too much milk can lead to iron deficiency anemia and protein loss from the gut.</li><li>Milk intake should be limited to a maximum of 500 mL (2 cups or 16 oz.) per day for toddlers and young children.</li><li>The main treatment for iron deficiency and protein loss from the gut due to excess milk intake is to reduce the amount of milk your child drinks and to increase the amount iron rich foods in their diet.

In Canada, it is seen in 3.5% to 10.5% of the general population. Children have a greater risk of iron deficiency anemia due to their rapid growth, particularly in the first two years of life.</p><p>Children who are most at risk of developing iron deficiency anemia are those who are fed only breast milk or non-iron fortified cow’s milk formulas after six months of age, and those who drink an excess of cow’s milk. Children who are given cow’s milk before 12 months may also be at increased risk of developing iron deficiency anemia because their gut may not be ready to digest cow’s milk yet.</p> <h2>Cause of iron deficiency anemia and protein losing enteropathy</h2><h3>Iron deficiency anemia</h3><p>Iron deficiency anemia from excessive milk intake is caused by three things.</p><ul><li><strong>Not enough iron:</strong> Milk contains very little iron. In addition, if a child drinks too much milk, they will be too full to eat good amounts of iron rich foods.</li><li><strong>Poor iron absorption:</strong> Milk and other dairy products can interfere with the gut’s ability to absorb iron from other sources, such as meat and meat alternatives, and dark green vegetables.</li><li><strong>Microscopic bleeding:</strong> Too much milk can damage the lining of the gut (milk enteropathy). Milk enteropathy causes microscopic bleeding from the gut that you may not be able to see. Any type of bleeding from the body results in a loss of iron. Over time, this bleeding can cause very low levels of haemoglobin, contributing to the iron deficiency anemia.</li></ul><h3>Protein losing enteropathy</h3><p>It is not fully understood how milk intake leads to protein loss in the gut. One theory suggests a process called villous atrophy. The small intestine part of our gut has finger-like projections on its walls called villi. The villi play an important role in the absorption of nutrients. It is believed that an excess intake of cow’s milk can cause the villi to shrink (villous atrophy) and not absorb nutrients well. Villous atrophy causes the bowel walls to become leaky, allowing protein to leak through.</p><h2>Diagnosis of anemia and protein losing enteropathy</h2><h3>Iron deficiency anemia</h3><p>Iron deficiency anemia can be diagnosed by your child’s doctor. They will do a physical exam and ask about your child’s energy levels, general health, diet and family history.</p><p>A blood test, called a complete blood cell count (CBC), can make the diagnosis of anemia by measuring haemoglobin levels.

Many toddlers enjoy drinking milk in a bottle, and associate drinking milk with their bedtime ritual.</p><p>Here are some tips on how to help limit your child’s milk intake:</p><ul><li>If your child drinks more than 1200 mL (5 cups or 40 oz.) of milk per day, wean them slowly to smaller amounts. Cut the amount by half to start.</li><li>Offer solid foods first and only offer milk at the end of the meal. Alternatively, you could offer water with meals and milk only a couple of times a day with a snack. This way your child will not fill up on milk first.</li><li>Switch to a sippy cup early. This will prevent your child from taking the milk to bed and associating drinking milk with falling asleep.</li><li>Do not allow your child to sleep with a bottle of milk in bed. If you are having trouble with this then slowly start to dilute the milk with water until you are offering just water. This will also help in avoiding dental caries.</li> </ul> <h2>Follow-up</h2><p>Iron supplementation should be continued for at least three to six months to replenish the amount of iron that is stored in the body.</p><p>After starting treatment, your doctor will schedule a follow-up appointment.
