Lack of sun isn't always the reason! Doctor Jesús Vázquez warns about low vitamin D levels: 'Inflamed intestine or irritated liver'

Spain, one of the countries with the highest number of hours of sunshine per year, has worrying levels of vitamin D deficiency among its population.

According to Dr. Jesús Vázquez, this deficiency is not always due to a lack of sun exposure, but may be linked to absorption problems caused by conditions such as inflamed bowels, irritated liver, or kidney problems.

Vázquez, on her personal Instagram account, noted that vitamin D is key to the immune system, calcium balance in bones, and the prevention of diseases such as senile dementia.

He warns that, even during the summer months, those already suffering from a deficiency should continue supplementation, especially those at risk, such as those over 65 or those with digestive pathologies.

According to data from the Spanish Nutrition Foundation (FEN), nearly 60% of people over 65 in Spain have insufficient vitamin D levels.

Deficiency is associated with an increased risk of osteoporosis, cardiovascular problems , and certain forms of cognitive decline.

Studies cited by the media show that between 40 and 50% of the general population may be deficient in this vitamin, even during periods of high solar radiation.

Factors such as aging, skin pigmentation, or diseases that hinder intestinal absorption reduce the body's ability to synthesize vitamin D, even with hours of sun exposure.

Therefore, specialists recommend not limiting oneself to solar radiation as the sole source and, in the case of a diagnosed deficiency, continuing supplementation and reviewing one's diet.
