Malabsorption Syndrome: Symptoms, Causes & Treatment

What is Malabsorption Syndrome?



Chronic diarrhea is usually the first symptom of malabsorption syndrome, prompting people to seek medical attention, but diarrhea doesn’t have to occur for a person to experience malabsorption. Fatty stools (steatorrhea) are also a sign of malabsorption syndrome. Feces may be foul smelling, frothy and may leave a circle of oil on the bathroom water.

The liver and gastrointestinal tracts play vital roles in nutrient digestion and absorption, as well as metabolism. Diseases of the liver and gastrointestinal tract may seriously upset normal nutrition.

Symptoms of Malabsorption Syndrome

The symptoms of malabsorption syndrome depend on the underlying cause, type of nutrient deficiency and how severe the deficiency is. Symptoms may appear quickly or develop gradually and get worse over time.

Some common symptoms seen with overall malabsorption include:

Chronic diarrhea

Failure to thrive (among children)

Abdominal pain, bloating, gas, and cramps

Greasy, loose and foul-smelling stools (steatorrhea)

Other symptoms may occur due to overall ill health or specific deficiencies caused by malabsorption syndrome. They can include:

Fatigue, weakness

Scaly and dry skin, rash

Ascites (fluid accumulation in the abdomen)

Glossitis (inflammation of tongue)

Unexplained weight loss, muscle wasting


Swelling of the legs, feet, and hands (peripheral edema)

Stomatitis (inflammation of mouth)


Bone or muscle pain

Bleeding gums, easy bruising

Tingling and numbness in the hands and feet


Causes of Malabsorption Syndrome

Malabsorption syndrome is caused by various diseases. Most of the time, it involves difficulty absorbing certain vitamins, proteins, fats or sugars. It may also involve a general problem in absorbing food.

Damage to or problems with the small intestine may lead to difficulty absorbing vital nutrients. These problems can include:

Crohn’s disease

Celiac disease

Whipple disease

Topical sprue

Tapeworm or parasite infection

Damage caused by radiation treatments

Bacterial overgrowth within the small bowel

Surgery that removes part of or the entire small intestine

Enzymes made by the pancreas aid the absorption of fats as well as other nutrients. When these enzymes are running low, it becomes more difficult to absorb some nutrients and fats. Various triggers may cause problems to the pancreas, including surgery to the pancreas, damage to the pancreas, cystic fibrosis and swelling or infections of the pancreas.

Other possible causes of malabsorption syndrome are:




Chronic liver disease

Intolerance to soy milk

Intolerance to cow’s milk protein

Certain medicines (some antacids, tetracycline, some obesity medicines, colchicine, phenytoin, cholestyramine, acarbose)

Treatment of Malabsorption Syndrome

Treatment options for malabsorption syndrome depend on the main cause. For example, a doctor will treat malabsorption due to lactose intolerance differently to malabsorption caused by liver disease. Most often, a low-fat, high-carbohydrate diet is ideal. It’s the easiest to digest as well as absorb.

In some cases, avoiding certain foods that worsen or trigger symptoms is the only treatment needed. For example, people with celiac disease can be treated by avoiding foods containing gluten, and those intolerant to lactose should steer clear of milk products.

Nutritional supplements can be prescribed. Common ones include vitamins K, E, D and A, iron, calcium and magnesium. Mineral and vitamin supplementation must be customized to individual needs, depending on clinical symptoms and serum levels.

To address the inadequate production of enzymes in the pancreas, pancreatic enzymes can be prescribed. Pancreatic enzymes come in tablets or capsules and, together with a low-fat diet, can benefit those with pancreatic disease.

To improve your digestion and absorption of nutrients, you can try the following natural ways to cope with malabsorption syndrome.

Chew Food Properly

Not chewing food properly can reduce the level of nutrients absorbed by your body from your diet.

Chewing properly allows your mouth to start the essential digestion process. Your food is broken down into smaller particles, so the fats and carbohydrates in your diet begin to be broken down by the saliva enzymes in your mouth. In addition, the saliva helps move your food smoothly through the intestines.

Eat More Fiber

Adults require not less than 30g of fiber daily from food only, yet most people get only around 15g of fiber a day.

Fiber provides numerous benefits, especially to people with malabsorption syndrome. By increasing your fiber consumption, you enhance digestion and shorten the time food lingers in your digestive system. As a result, your body gets ample time to process as well as absorb essential nutrients.

Some excellent fiber sources include leafy green vegetables, legumes (kidney beans, black beans, pinto beans) and whole grains (quinoa, sprouted wholegrain bread, and steel-cut oatmeal).

Take Digestive Enzyme Supplements

Digestive enzymes are substances that help the body break down certain nutrients and may help your body absorb more of the vital nutrients from foods.

For carbohydrate absorption, take enzymes like sucrase, lactase (perfect specifically for people with lactose intolerance), cellulase, amylase and maltase. For protein digestion, consider papain and bromelain. And for fat digestion, consider lipase.

The Bottom Line

Malabsorption syndrome occurs when your body is unable to digest and absorb food correctly, depriving your body of essential nutrients required for sustenance and growth. This disorder is often characterized by symptoms like unexplained weight loss and persistent diarrhea.

Many conditions can cause malabsorption syndrome. In most cases, malabsorption has to do with difficulty absorbing certain fats, sugars, vitamins or proteins. It may also have to do with an overall issue with absorbing food. Conditions that can make the small intestine unable to absorb vital nutrients include celiac disease, Crohn’s disease, tropical sprue, Whipple disease, excessive growth of bacteria in your small bowel and tapeworm or parasite infection.

Symptoms of malabsorption syndrome can be mild or severe and normally occur in the digestive tract, where absorption of nutrients is supposed to take place. These digestive tract symptoms include abdominal pain, bloating, gas and cramps, as well as chronic diarrhea. Other malabsorption symptoms include fatty, loose, foul-smelling stools (steatorrhea) and failure to thrive (among kids).

When the underlying cause of malabsorption syndrome is treatable, the main aim of treatment is to address the cause. At first, the doctor may recommend avoiding the type of food causing the problem, such as food containing lactose or gluten. The doctor may assess the nutrients contained in this food and recommend supplementation as a way of boosting nutritional intake.
