  • If you start to lose weight, read below for practical suggestions on gaining weight. Ask for a referral to a dietitian if weight loss is an ongoing and significant issue.
  • Do some light physical activity, such as walking, to improve appetite and mood, reduce fatigue, help digestion and prevent constipation.
  • Check with your doctor or dietitian before taking vitamin or mineral supplements or making other changes to your diet.

After treatment
