Malabsorption: Causes, Risk Factors, Symptoms, Treatment


Malabsorption is an important term for a wide range of disorders that affect your ability to absorb nutrients from your food. Malabsorption can lead to indigestion and even malnutrition. The digestion has a three-part process; the first part is breaking down food into digestible pieces, the second part is absorbing all the nutrients in your food and the third part is eliminating the waste that is left over when all the good substance has been absorbed. If there is any digestive difficulties, the problem could be in any of these three stages (or several). Malabsorption disorders cover the second stage. They include specific food intolerances caused by enzyme deficiencies, as well as various gastrointestinal diseases that affect the digestive system.

Symptoms of Malabsorption

If you suspect you or someone else is experiencing Malabsorption, it is crucial to seek immediate medical attention by calling emergency services or consult with a Nutritionist.


Normally, the absorption of most of the nutrients into the bloodstream through the wall of small intestine as partially digested food works its way through the digestive system. The absorption of the rest of the nutrients is through the large intestine. The blood then carries nutrients, such as calcium or protein, to the bones, muscles, and organs. Then it expels what’s left over through the rectum.

Risk Factors

Risk factors for malabsorption syndrome include: Ø a family history of cystic fibrosis or malabsorption Ø drinking large amounts of alcohol Ø intestinal surgery Ø use of certain medications, including laxatives or mineral oil Ø travel to the Caribbean, India, and parts of Southeast Asia


Malabsorption is a condition that occurs when the body is unable to properly absorb nutrients from the food we consume. It can lead to various symptoms and complications, making it crucial to understand its signs and seek appropriate medical attention. One of the key symptoms of malabsorption is unexplained weight loss. When the body fails to absorb essential nutrients like fats, proteins, and carbohydrates, it can result in unintended weight loss despite maintaining a regular diet. Another common symptom is diarrhea or loose stools. Malabsorption can disrupt the normal digestive process, leading to frequent bowel movements and watery stools. This occurs as undigested food passes quickly through the intestines without being properly absorbed. Individuals with malabsorption may also experience abdominal pain or discomfort. This can range from mild discomfort to severe cramping, often accompanied by bloating or excessive gas. These symptoms occur due to the improper breakdown and absorption of food in the gastrointestinal tract. Also, malabsorption can cause deficiencies in vital vitamins and minerals such as vitamin D, vitamin B12, iron, and calcium. These deficiencies may manifest as fatigue, weakness, brittle bones (osteoporosis), anemia, or even neurological symptoms like tingling sensations or muscle weakness. If you are experiencing any of these symptoms persistently or have concerns about malabsorption, it is important to consult with a healthcare professional for proper diagnosis and treatment options. Early detection and management can help improve your overall health and prevent further complications associated with malabsorption.

There are several tests to find the cause of the problem. These include: Ø Stool test: Too much fat in the stool could cause malabsorption. Ø Lactose hydrogen breath test: this can show absorption of nutrients by measuring how much hydrogen is in the breath after drinking milk (lactose) solution. Ø Sweat test: Studying a sample of sweat can help diagnose cystic fibrosis. One of the effects of that disease is a lack of enzymes to properly digest food. Ø Biopsy of small intestine: A small tissue sample is taken from inside the small intestine and studied to see whether it shows signs of infection or other problems. Ø Endoscopy: A long, flexible tube with a camera is used to check the intestine.


Treatment for malabsorption syndrome depends on the cause. A special diet of foods that are more easily digested and absorbed can be started. Also the supplements can be given to make up for nutrients that aren’t being absorbed well. Sometimes the cause of malabsorption syndrome is an intestinal tract that is too active. Medicines may be prescribed to help it relax and allow more time for nutrients to enter the bloodstream. If an infection is the cause, antibiotics are prescribed.

Preventive Measures

Malabsorption syndrome can’t always be prevented, especially if it has celiac disease, cystic fibrosis, or other chronic conditions. A chronic condition is one that is ongoing and lasts a long time, from several months to a lifetime. The usage of laxatives and antibiotics carefully and only when necessary. And consult a doctor or a dietitian before starting a special diet, rich in nutrients required by the body.

Do's & Don’t's

When it comes to managing malabsorption, there are certain do's and don'ts that can greatly impact your overall well-being. By following these guidelines, you can better support your body's ability to absorb essential nutrients and alleviate symptoms associated with malabsorption. 

Do's Don't
Work with a healthcare professional to identify and manage the underlying cause of malabsorption. Avoid self-diagnosis or self-treatment without medical guidance.
Follow a prescribed diet plan recommended by a registered dietitian or healthcare provider. Don't consume large amounts of high-fat or high-fiber foods that could exacerbate symptoms.
Take prescribed supplements (e.g., vitamins, minerals) as advised by a healthcare professional. Avoid excessive alcohol consumption, which can worsen malabsorption.
Stay hydrated by drinking plenty of fluids unless otherwise directed by a healthcare provider. Don't skip or neglect prescribed medications without consulting a healthcare professional.
Consume easily digestible foods such as cooked vegetables, lean proteins, and easily absorbable carbohydrates. Avoid foods known to trigger symptoms or worsen malabsorption, based on personal tolerance.
Eat smaller, more frequent meals throughout the day to aid digestion and absorption. Don't rely solely on over-the-counter digestive aids or supplements without medical advice.
Keep a food diary to track symptoms and identify potential trigger foods or patterns. Avoid excessive caffeine intake, as it can exacerbate gastrointestinal issues.
Practice good food hygiene, such as washing hands before eating and properly storing and preparing food. Don't ignore symptoms like diarrhea, abdominal pain, or nutrient deficiencies; report changes to your healthcare provider promptly.
Consider alternative cooking methods like steaming, baking, or grilling instead of frying to reduce fat intake. Avoid high-lactose dairy products if lactose intolerance is contributing to malabsorption.
Engage in stress-relieving activities like yoga, meditation, or exercise to manage stress, which can impact digestion. Don't overlook the importance of regular follow-ups with healthcare providers to monitor progress and adjust treatment as needed.

Frequently Asked Questions
Malabsorption is a condition where the digestive system is unable to properly absorb nutrients from the food you eat. This can lead to deficiencies in essential vitamins, minerals, and other nutrients.
Malabsorption can be caused by various factors, including gastrointestinal disorders such as celiac disease, Crohn's disease, and irritable bowel syndrome (IBS). Other causes may include pancreatic disorders, liver diseases, and certain medications.
Symptoms can vary but may include diarrhea, weight loss, abdominal pain, bloating, fatigue, and deficiencies in specific vitamins or minerals.
Diagnosis typically involves a combination of medical history, physical examination, blood tests, imaging studies, and sometimes endoscopy or biopsy to identify the underlying cause.
Treatment depends on the underlying cause. It may involve dietary changes, nutritional supplements, medications to manage symptoms or address the underlying condition, and in some cases, surgery.
The small intestine is a key player in nutrient absorption. Conditions that affect the lining of the small intestine, such as celiac disease or inflammation, can lead to malabsorption.
Yes, certain populations may be more susceptible, including individuals with autoimmune diseases, a family history of malabsorption disorders, or those who have undergone gastrointestinal surgeries.
Malabsorption can lead to deficiencies in specific nutrients like iron, vitamin B12, calcium, and others. These deficiencies can result in a range of health issues, including anemia and bone disorders.
No, they are different. Malabsorption refers to the body's inability to absorb nutrients, while food intolerance involves difficulty digesting specific types of food, often due to enzyme deficiencies.
Prevention depends on the underlying cause. For some conditions, such as celiac disease, strict adherence to a gluten-free diet may prevent malabsorption. Regular check-ups and early intervention for gastrointestinal issues can also help.
