What does the malabsorption of fat cause?

Fat malabsorption Fats that aren’t absorbed in your small intestine pass to your colon, causing fatty stools (steatorrhea). Fatty stools are greasy and runny and particularly smelly. They may be light-colored and float. Fat malabsorption also leads to the malabsorption of fat-soluble vitamins (A, D, E and K).

What deficiencies cause malabsorption?

Factors that may cause malabsorption syndrome include:

  • damage to the intestine from infection, inflammation, trauma (injury), or surgery.
  • prolonged use of antibiotics.
  • other conditions such as celiac disease, Crohn’s disease, chronic pancreatitis, or cystic fibrosis.
  • lactase deficiency, or lactose intolerance.

Does fat malabsorption cause vitamin D deficiency?

Given that vitamin D is fat soluble and absorbed in the proximal small intestine, it has been documented that vitamin D deficiency in people with a fat malabsorption syndrome is due to decreased absorption of vitamin D.

What are the consequences of malabsorption of lipids?

The small intestine plays a key role in lipid metabolism by absorbing fat and synthesising apoproteins. Fat malabsorption secondary to intestinal disease results in abnormalities of lipoprotein concentration and composition and can lead to deficiency of essential fatty acids and fat-soluble vitamins.

What vitamin deficiency can cause diarrhea?

Vitamin B-12 deficiency can affect the digestive tract. A lack of red blood cells means that not enough oxygen reaches the gut. Insufficient oxygen here may lead to a person both feeling and being sick. It may also cause diarrhea.

Is vitamin D deficiency malnutrition?

Vitamin D deficiency is common in children with severe acute malnutrition, in whom it is associated with severe wasting. Ready-to-use therapeutic food (the standard treatment) contains modest amounts of vitamin D that do not reliably correct deficiency.

What nutritional parameters would be affected by the fat malabsorption?

Fat malabsorption can lead to low serum levels of triglycerides, cholesterol, and alpha- and beta-carotene.

What complications may develop if the fat malabsorption is not controlled?
