Good nutrition is an important part of the overall treatment plan for your lupus. A well-balanced diet provides the necessary fuel for your body to carry on its normal functions. Although there are no specific dietary guidelines for people with lupus, there are some nutrition issues that you should know about. If any of these issues become a problem for you, talk with your doctor or nurse. They will be able to provide you with additional information and can refer you to a registered dietitian if necessary.

Weight loss or poor appetite: weight loss over the previous year is commonly reported by people who are newly diagnosed with lupus. Weight loss and poor appetite can be caused by the illness itself or by some medications that may cause stomach upset or mouth sores (also called mouth ulcers).

Your doctor or nurse will assess your weight loss and other related problems and suggest changes in your diet to be sure that you are eating right and have no further weight loss.

Weight gain: Weight gain may be a problem for people who take corticosteroids. These drugs often increase a person’s appetite, and, unless you are careful, unwanted weight gain will occur.

Your doctor or nurse will assess your diet and other related problems and can suggest a program to help you control your weight and loss any unwanted pounds. The program will probably include a low-fat diet, exercise, and behavior modification a registered dietitian can help you evaluate your food likes and dislikes and eating patterns and can design a diet specifically for your needs and lifestyle.

Difficulty taking medications: several medications can cause gastrointestinal (GI) disturbances, such as heartburn, upset stomach, nausea, vomiting, or painful mouth ulcers.

If you are having GI problems, tell your doctor or nurse immediately. Because many of these problems are related to how and when a medication is taken, the dose or schedule can sometimes be changed to reduce or stop the unpleasant side effects. In some cases, the doctor may change the drug. Many medications can be taken with food, which helps reduce side effects. If you have mouth ulcers, liquid forms of the drugs you are taking may be available. In addition, anesthetics you can use in your mouth can decrease the pain of mouth ulcers and make swallowing easier.

Osteoporosis: Osteoporosis is a condition in which the bones of the body become less dense and break easily. Although this condition often affects older, postmenopausal women, it can also affect anyone who takes corticosteroids for a long period of time.

Your doctor or nurse will review your medical history, treatment plan, diet, and any risk factors you may have. Measurements of your bone density may also be taken. Recommendations to prevent or reduce the problem will probably include a diet high in calcium (1,000-1.500 mg/day) and vitamin D (100-500 mg/day) and an exercise plan that is appropriate for you. Calcium supplements may be prescribed by your doctor if the calcium in your diet is not enough.
