The Malabsorption Blood Test (MBT), consisting of pentadecanoic acid (PA), a free fatty acid and triheptadecanoic acid (THA), a triglyceride that requires pancreatic lipase for absorption of the heptadecanoic acid (HA), was developed to assess fat malabsorption in patients with cystic fibrosis (CF) and pancreatic ...
Hematologic tests indicated in the workup of malabsorption include the following: A complete blood cell (CBC) count may reveal microcytic anemia due to iron deficiency or macrocytic anemia due to vitamin B12 (cobalamin) or B9 (folate) malabsorption.
Stool tests.
A stool test can measure the fat content in your stools to diagnose fat malabsorption. It can also reveal parasitic infections, and it can show evidence of decreased pancreatic function.
A xylose test is most often used to: Help diagnose malabsorption disorders, conditions that affect your ability to digest and absorb nutrients from food.
The D-xylose absorption test measures the level of D-xylose, a type of sugar, in a blood or urine sample. This test is done to help diagnose problems that prevent the small intestine from absorbing nutrients in food.
Malabsorption is when your body has trouble digesting food and absorbing nutrients. Common symptoms include bloating, weight loss, fatigue, muscle weakness, abdominal discomfort, bad smelling stools, rashes, swollen feet and hands, and nausea and vomiting.

Chronic diarrhea is the most common symptom and is what usually prompts evaluation of the patient. Steatorrhea—fatty stool, the hallmark of malabsorption—occurs when > 7 g/day of fat are excreted. Steatorrhea causes foul-smelling, pale, bulky, and greasy stools.
Treatment may include diet changes and supplements. If left untreated, malabsorption syndrome can cause complications like a weak immune system, nutrient deficiencies, and osteoporosis.
Steatorrhea—fatty stool, the hallmark of malabsorption—occurs when > 7 g/day of fat are excreted. Steatorrhea causes foul-smelling, pale, bulky, and greasy stools.
Regardless of the cause, malabsorption syndrome refers to the clinical picture comprising diarrhea, steatorrhea, malnutrition, weight loss, abdominal pain, and anemia. Undigested food produces diarrhea, due to its voluminous effect in the bowel lumen.
Symptoms and Signs of Malabsorption
Chronic diarrhea is the most common symptom and is what usually prompts evaluation of the patient. Steatorrhea—fatty stool, the hallmark of malabsorption—occurs when > 7 g/day of fat are excreted. Steatorrhea causes foul-smelling, pale, bulky, and greasy stools.
Symptoms of Malabsorption
When there is inadequate absorption of fats in the digestive tract, stool contains excess fat and is light-colored, soft, bulky, greasy, and unusually foul-smelling (such stool is called steatorrhea).
DDX. Malabsorption, also known as leaky gut or intestinal permeability, can be the result of multiple different issues.
Probiotics could help maintain a eubiotic environment, correct dysbiosis, and ameliorate nutrient malabsorption issues within the SI.
Chronic diarrhea is often the first symptom prompting one to seek medical evaluation, although diarrhea need not be present for one to have malabsorption. Steatorrhea, or fatty stools, is indicative of malabsorption. Stools will be frothy, foul smelling, and a ring of oil may be left on the toilet water.
There are three stages of nutrient absorption: luminal, mucosal, postabsorptive. Malabsorption syndromes are categorized according to which of these three stages is or are affected.
When it's not treated, malabsorption syndrome might lead to: Greater chance of infections. Osteoporosis (low bone density), which increases risk of bone fractures. Slower growth and weight gain in children.
Phytates (phytic acid) in whole grains, seeds, legumes, some nuts—can decrease the absorption of iron, zinc, magnesium, and calcium. [2,3] Saponins in legumes, whole grains—can interfere with normal nutrient absorption.
IBS symptoms can result from malabsorption of fructose. Fructose is a monosaccharide found naturally in small quantities in fruits and some vegetables, and in much larger quantities in industrially manufactured sweets with added sugars (e.g. sucrose and high fructose corn syrup).
Vitamin D deficiency in patients with intestinal malabsorption syndromes--think in and outside the gut.
Colonoscopy is the investigation of choice for diagnosis. Even a macroscopically normal mucosa on endoscopy can have abnormalities such as microscopic colitis and bile acid malabsorption (BAM).
