Thursday, March 17th, 2011Constipation
Some anti-cancer drugs and other drugs, such as pain medicines, may cause constipation. This problem may also occur if the diet lacks enough fluid or bulk or if bedridden.
To prevent and treat constipation the patient should:
1. Drink plenty of liquids – at least 8-9 glasses every day. This will help to keep stools soft.
2. Take a hot drink about half an hour before usual time for a bowel movement.
3. Eat high-fibre foods, such as whole grain breads, cereals, fresh fruits and vegetables; dried beans and peas; and whole grain products such as barley or brown rice.
4. Eat the skin on fruits and potatoes.
5. Get some exercise, such as walking, everyday. Talk to the doctor or a physical therapist about the amount and type of exercise that is right for you.
6. Add unprocessed wheat bran to foods such as cereals.
If these suggestions do not work, doctor should recommend medicine to ease constipation. The patient should check with the doctor before taking any laxatives or stool softeners.
Weight gain
Sometimes, patients gain excess weight during treatment without eating extra calories. For example, certain anticancer drugs, such as steroids, can cause the body to hold on to fluid causing weight gain, this condition is known as oedema. The extra weight is in the form of water and does not mean one is eating too much.
It is important not to go on a diet if weight gain is noticed. Instead, doctor should find out what may be causing this change. If anti-cancer drugs are causing the body to retain water, the doctor may ask the patient to speak with a dietitian. The dietitian can teach how to limit the amount of salt eaten, which is important because salt causes the body to hold extra water. Drugs called diuretics may also be prescribed to get rid of extra fluid.
