We are all aware that low levels of vitamin D can cause weak bones. A recent study indicates that it could be associated with liver disease as well!

Low Vitamin D Levels Could Cause Liver Disease

Researchers claim that low vitamin D could be one of the reasons behind the development of non-alcoholic fatty liver disease (NAFLD).  NAFLD occurs due to accumulation of triglycerides in the liver cells.

Outpatients of suspected metabolic syndrome with normal liver enzymes, no excessive alcohol intake, negative for hepatitis B and hepatitis C, no cirrhosis or chronic liver disease were subjected to liver ultrasound to estimate the presence and degree of fatty liver disease.  25(OH) vitamin D levels were measured to estimate any deficiency of vitamin D.

The researchers found that patients with NAFLD had low levels of 25(OH) vitamin D.  They also found that the lower 25(OH) vitamin D levels, the worse is the degree of fatty liver disease.  This association was independent of other possible influencing factors like age, sex, triglycerides, HDL and fasting blood glucose levels. 

Vitamin D suppresses fibroblast (cell from which connective tissue develops) proliferation and collagen production, thus acting as an immune-modulator.  It also appears to have a beneficial effect in patients with hepatitis C on treatment with interferon.

Vitamin D normally plays a role in the metabolism of free fatty acids.  Thus, the researchers suggest that in people with low vitamin D levels, the excess free fatty acids flow in the blood stream.  These deposit in the liver, resulting in NAFLD.  Vitamin D's anti-inflammatory properties and reduction in insulin resistance could also play an important role.

Further studies are warranted to evaluate whether administration of vitamin D in patients with NAFLD could help to treat it, thus firmly establishing the association between fatty liver disease and vitamin D.

I have been diagnosed with end stage cirrhosis of the liver and blood test indicates low Vit. D. I have also been advised several times to take Vitamin D supplements. Each time I have used supplements nausea has been experienced. Is their some relationship to the disease and vitamin D?

Vitamin D is essential for the growth, bone development, and health of infants and young children. To see how prevalent vitamin D deficiency is, researchers tested blood vitamin D [25OHD] levels in 380 infants and toddlers at one of their routine health visits.
To make sure your infant or child is getting adequate vitamin D, be sure they get at least 10 minutes in the bright sunshine on bare skin daily or take a vitamin D supplement especially in winter months, or both. Just be sure the infant doesn't get any sunburn.Gradually expose the infant over several days to just a few minutes of sun exposure to build up their tolerance for 10 minutes at a time. Multiple short exposures are safer than a single, long exposure to the sun.
