In-depth information concerning the issues that may arise for your child if he gains too much weight as a side effect of his brain tumour treatment.

Key points

  • Children with brain tumours may gain weight due to steroid use, tumour type, hypothyroidism.
  • Try to maintain a healthy weight by being as active as possible and establish healthy eating patterns.

A number of factors can cause weight gain in children with brain tumours:

  • Steroid use: some of the weight gained is caused by water retention, which will be lost when steroid use is stopped.
  • The treatment or type of tumour: children with a tumour located near the hypothalamus may develop uncontrollable appetites. The hypothalamus is a part of the brain that controls eating and appetite.
  • Untreated or undiagnosed hypothyroidism: low levels of thyroid hormones cause the body's metabolism to slow down.
