Vitamin B5 deficiency

Vitamin B5 is also known by the name of pantothenic acid. When someone does not get a sufficient amount of this, then a vitamin B5 deficiency may occur. This absence of a proper amount, however, is particularly rare. This may be due to the fact that the vitamin is found in small amounts in many different foods.


A number of possible symptoms can occur when a person has a vitamin B5 deficiency. Paresthesia is one that might show up. Some are mentioned below, but this is not intended to be an exhaustive list. Additionally, since other conditions can lead to these, the fact that such medical signs are present in a patient does not indicate that a lack of pantothenic acid is the reason.

Abdominal cramps
Muscle cramping
Nausea / vomiting
Various neurological symptoms

Many symptoms involved are similar to those found in other deficiencies of B-complex vitamins. When these signs do occur, they can typically be reversed by providing the individual with pantothenic acid.


Lacking proper amounts of vitamin B5 can also lead to some complications. For instance, a person might end up with hypoglycemia (incidentally, another possible cause of paresthesia). In hypoglycemia, the person has a blood sugar level which is lower than normal. Rarely, serious complications can occur. Hepatic encephalopathy and adrenal insufficiency are two such examples, and both are reversible. The former issue is one in which there may be confusion, changed consciousness levels, and even coma. It can be fatal in some cases. In the latter condition, the adrenal glands do not produce sufficient levels of certain hormones -- in particular cortisol.

Similar condition

Another related condition which can be a cause of paresthesia is a vitamin B12 deficiency.
