Effects of vitamin D deficiency in adults

This is an automatically translated article.

Vitamin D helps the body absorb calcium and phosphorus well to form and maintain strong bones and teeth. Vitamin D deficiency in adults and especially vitamin D deficiency in women causes many diseases such as weak bones, osteoporosis. Recently, studies have also shown that vitamin D deficiency can be a risk factor for many diseases outside the skeletal system such as infections, cancer, diabetes. Below are the specific effects of vitamin D deficiency in adults.

1. Vulnerable to infection

Vitamin D is important for the health of the immune system. Vitamin D deficiency in adults causes our immune cells to not respond appropriately, making us more susceptible to infections. Vitamin D is essential for the function of two basic parts of the immune system, adaptive and innate immunity.
Adaptive immunity is about remembering which viruses you have - chickenpox for example - and making sure you don't get them again. Both of these immune systems are essential and both require adequate levels of vitamin D to function.
If you feel that your body is susceptible to infection, you can do tests to supplement the vitamin D you need. Currently, scientists are studying the role of vitamin D deficiency in increasing the risk of cancer, especially colorectal cancer, breast cancer, pancreatic cancer and prostate cancer.

2. The body is always tired

Vitamin D is essential for converting food into energy. Without this vitamin, the body will not absorb nutrients from food and as a result, lack of energy.
Vitamin D deficiency in women will easily lead to mood and mood swings like during menstruation. So, if you experience mood swings without any logical explanation, you may have a vitamin D deficiency.
A randomized placebo-controlled clinical trial recently published in the journal Medicine found that vitamin D supplementation significantly improved fatigue levels.

3. Joint pain or weak bones

Vitamin D is needed to regulate calcium and phosphate levels in the body, plays a key role in the proper functioning of joints, muscles and teeth and in proper levels helps prevent osteomalacia (soft bones) and osteoporosis (loss of bone density).
Vitamin D deficiency in adults leads to bone problems, characterized by bone loss, bones becoming weaker and prone to thinning. Bone mineral density is also reduced and bones become very weak, affecting bone structure and osteoporosis.
Vitamin D deficiency in postmenopausal women have a higher risk of bone diseases, especially osteoporosis because the body has difficulty absorbing vitamin D.
If you have osteoporosis due to vitamin deficiency D in women, you should increase vitamin D-rich foods into your diet and get more sun exposure. However, you should avoid sunbathing from 10 am to 6 pm because during this time, the sun has a lot of ultraviolet rays that are harmful to the skin.
A 2014 study found that adults over 50 with vitamin D deficiency are more likely to experience pain in the hip and knee joints, and the pain is likely to get worse if the anemia is left untreated.

4. Damaged muscles

Vitamin D supports muscle function because its receptors are located throughout the body, including in the muscles. There are many general muscle aches that are a sign of vitamin D deficiency. Vitamin D enters muscle cells as it is metabolized, enhances muscle contraction, is important for preventing falls and building muscle. muscles and bones through exercise.
In fact, researchers have found a link between chronic pain unresponsive to treatment and vitamin D deficiency in adults, and vitamin D supplementation has been shown to help.

5. Cancer

Vitamin D deficiency in adults may be associated with cancer. One study has shown that more than 75% of people with various types of cancer have low vitamin D levels, and the lowest levels occur in patients with advanced cancer. However, this research still needs to be continued because there is no evidence on whether high vitamin D levels reduce the risk of cancer or cancer death.

6. Polycystic Ovarian Syndrome

Vitamin D deficiency may contribute to the pathogenesis of polycystic ovary syndrome by promoting insulin resistance. Long-term vitamin D deficiency in women also increases parathyroid hormone (PTH) production, increases free testosterone levels, can affect intracellular calcium metabolism contributing to dysfunction. ovulation and negatively impact fertility.
Numerous studies in humans and animals have shown that vitamin D is associated with reproductive function in both women and men, in part because vitamin D receptors and vitamin D-metabolizing enzymes have been found in reproductive tissue in humans. Some scientific evidence also shows an association between vitamin D and indicators of ovarian reserve.
Vitamin D supplementation may be an essential element in the understanding and treatment of disorders and complications in subjects with polycystic ovary syndrome, in order to prevent serious health consequences. . Studies have shown that vitamin D supplementation can reduce androgen levels, increase insulin sensitivity, and contribute to improved pregnancy in women with polycystic ovary syndrome.
