AIDS wasting syndrome
AIDS wasting syndrome causes a person to lose body weight and muscle.
AIDS wasting syndrome is not a specific condition, but is a poorly understood side effect of AIDS.
What causes AIDS wasting syndrome?
If you have AIDS, the following factors can work together to promote weight loss.
Not eating enough. It may be difficult to get adequate nutrition for reasons such as these:
- Poor appetite from HIV infection
- Side effects of medicines, such as nausea, changes in taste, or tingling of the mouth
- Opportunistic infection symptoms, such as a painful throat or sense of fullness
- Lack of money or energy to shop for and prepare meals
Not absorbing nutrients well. This may happen because:
- HIV directly affects the intestinal lining.
- Opportunistic infections interfere with absorption.
- Medications cause diarrhoea, which leads to a loss of calories and nutrients.
Changes in metabolism. This can occur for many reasons.
- HIV disease burns calories quickly, so you need more calories to maintain your body weight. This need for extra calories may be due to the increased activity of the immune system. Or it may be because HIV changes levels of hormones that affect how fast you burn calories.
- People with HIV have high levels of proteins called cytokines. These make your body produce more fats and sugars, but fewer proteins.
Diagnosing AIDS wasting syndrome
To diagnose AIDS wasting syndrome, your doctor will ask you about your history, finding out about your diet, the medications you're taking, and whether you've been depressed, for example.
You may also have tests to identify problems with nutrient absorption.
Treating AIDS wasting syndrome
It's important to monitor your weight and maintain healthy eating habits - even when you're not hungry. Seek medical advice straight away if you lose weight, have severe diarrhoea, or have an opportunistic infection affecting your gastrointestinal system.
To treat AIDS wasting syndrome, your doctor will use a variety of approaches:
Medication to increase appetite, or reduce nausea and vomiting, or to relieve diarrhoea.
Identify and treat opportunistic infections that affect the intestines.
- Make adjustments in your HAART medications.
- Suggest nutritional supplements to help make up for poor nutrient absorption.
- Suggest limiting fat, lactose, insoluble fibre (such as that found in fruits, vegetables, and whole grains), caffeine, alcohol, and concentrated sweets.
Progressive resistance training (PRT) also can be helpful in increasing lean body mass. This involves gradually increasing weight, repetitions, or sets to improve strength.
