Many patients with ankylosing spondylitis will suffer from anorexia.

Anorexia means a loss of appetite. Anorexia is a persistent problem with many chronic diseases. It is also a common side effect of many medications used to treat chronic disease.

Good nutrition is an important part of a successful treatment program. Home care for anorexia includes:

• Avoid stomach irritants such as aspirin or ibuprofen.
• Avoid excessive caffeine and other stimulants.
• Check with your doctor about drinking alcohol.
• Do not force yourself to eat at standard times. Eat when you are hungry instead.
• Concentrate on eating a healthy diet. Avoid junk foods.
• Select healthy, high-calorie foods that you enjoy.
• Eat more frequent, smaller meals.
• Get some exercise every day.
• Keep a daily log of your weight.
• Don't smoke. Nicotine can suppress the appetite.
• Ask your doctor or nutritionist about dietary supplements.
• Ask your doctor if any medications you may be taking can cause anorexia.
• Take any prescribed medications as directed.
• Anti-nausea medications:
• Compazine
