Diarrhea is an increase in the water content, frequency, and volume of bowel movements. It is frequent in people with HIV disease.
Diarrhea can be a serious problem. Mild cases disappear within a few days. Severe cases can cause serious dehydration or nutritional problems.
The greatest risk of diarrhea is dehydration. You can lose up to a gallon of water each day. Along with the water, you lose minerals (electrolytes) that are important for normal body functions. The main electrolytes are sodium and potassium.
Severe dehydration can cause the body to go into shock and is potentially fatal. Dehydration is more serious for infants and children than for adults. Anyone with diarrhea should drink plenty of clear liquids. Tea, chicken broth, ginger ale, or soda are good choices. These are better than plain water, which does not replace any electrolytes.
Diarrhea that continues over a long period of time can cause poor absorption of nutrients. This can lead to wasting. (See Fact Sheet 519).
Diarrhea can be dangerous. Be sure your healthcare provider knows if your diarrhea lasts more than a few days.
It can be difficult to find out what is causing diarrhea. Diarrhea is sometimes caused by an infection in the stomach or intestines. It can also be caused by an inability to digest milk products (lactose intolerance), by problems with the pancreas, or by emotional stress. Bacteria, parasites, fungi, or viruses can cause the infection.
Your health care provider will ask you what you have been eating and drinking recently, and whether you have been travelling. Samples of your bowel movement (or "stool") may be tested for signs of bacteria or parasites. Your health care provider may repeat this test if nothing shows up the first time. In some cases your blood or urine will also be tested.
If these tests do not show the cause of diarrhea, your health care provider may look inside your digestive tract with a special tool or scope. The name of this procedure depends on where the health care provider is looking. "Endoscopy" is a general term that means "to look inside." A colonoscopy is a procedure where the health care provider examines the colon, and so on. The cause of about one third of all cases of diarrhea cannot be determined.
1. Change What You Eat: Some foods can cause diarrhea, and others can help stop it.
2. Drug Treatments: A new treatment for HIV-associated diarrhea is Fulyzaq (crofelemer). It was approved by the FDA late in 2012. Different medications are used to treat different types of diarrhea. Your health care provider may not be able to prescribe a medication without some idea of what is causing your diarrhea.
You do not need a prescription for over-the-counter treatments. Some of these work very well for diarrhea, including:
Some other products that are usually sold to treat constipation can also help with diarrhea. These products contain "soluble" fiber that adds bulk and absorbs water. This includes products like Metamucil, Citrucel, or other products that contain psyllium.
3. Alternative Therapies for Diarrhea: Acidophilus capsules (which contain helpful bacteria) can help restore normal digestion, especially when you are taking antibiotics. Some types of yogurt contain "live cultures" of acidophilus that work the same way.
Peppermint, ginger and nutmeg are believed to help with digestive problems. Peppermint or ginger tea or ginger ale would be good choices for "clear liquids." Try adding nutmeg to your food or drinks.
Studies have shown that calcium supplements helped relieve diarrhea in people taking nelfinavir (Viracept). This might work for diarrhea caused by other medications.
Diarrhea is a common problem for people with HIV. It is usually caused by an infection in the digestive system. Stress, some medications, or problems digesting milk products can also cause diarrhea.
The most serious result is dehydration. This is more of a problem for children than for adults. If you have diarrhea, you should drink plenty of clear liquids.
Some simple changes in your food can help with diarrhea. So can some over the counter medications or acidophilus.
Be sure you tell your health care provider if your diarrhea lasts more than a few days.
