"Sun vitamin", as vitamin D is also called, since we get its purest form from the sun, is a fat-soluble vitamin whose regular and controlled intake is the best for our health. And indeed, this vitamin provides us with many benefits by strengthening our immune system, helping the absorption of calcium, having a beneficial effect on nerves and bones, providing us with a good mood, improving the quality of the skin and many other things that function properly with its intake. But what happens when we have a lack of vitamin D and how does it affect our body? The text in front of you contains all the information, so let's start in order. Vitamin D deficiency - symptoms The body often sends us clear signals when a certain change is happening in it, but we usually attribute it to fatigue or stress and continue to live with it until it starts to seriously affect our health. That is why the best measure is to react to these signals immediately and ask ourselves what is behind them. In this particular case, vitamin D deficiency manifests itself in the following ways: you are often exhausted during the day - even if you actually got enough sleep, even more than the 8 hours that are considered regular during the night you often get sick - because precisely the lack of this vitamin makes you vulnerable and prone to viruses and infections your bones, joints and muscles often hurt - which indicates that you lack vitamin D, since this vitamin is also important for the absorption of calcium, as we have already stated in the introduction of this text. With its deficiency, bones become brittle, soft, and then painful you are prone to depressive feelings - according to certain studies, vitamin D deficiency is one of the causes of depression in the event of an injury, your wounds heal slowly - in order for wounds to heal as quickly as possible, you need a lot of nutrients, and among them is vitamin D, which protects against infections your hair falls out more - which happens if you suffer from stress-induced alopecia, which is then linked to a lack of vitamin D in your body you feel pain in your muscles as after strenuous exercise - which also manifests itself as a deficiency of vitamin D, and they become quite sensitive, sometimes to the extent that the pain affects your daily functioning because movement is difficult.

It is a degenerative joint disease accompanied by constant pain, limited mobility and difficulty in daily functioning. This disease is caused by the accumulation of calcium on the edges of the bones of the joints, which causes impaired mobility, which appears as the first clear symptom. The hip and knee joints are mostly affected because they bear the greatest load. It also occurs more often in women after the age of 40. It is believed that the lack of vitamin D in women is one of the common causes of this disease. See below how the lack of this vitamin affects the skin, in addition to the already mentioned alopecia and slower wound healing. Vitamin D deficiency - symptoms on the skin The skin, as our largest organ, is considered the first line of defense, so if you notice certain damages on it, it is a clear signal that there is a problem. Here's how vitamin D insufficiency affects the condition of our skin: dry skin - exactly vitamin D has a key role in hydration and in preserving the skin barrier. When the body suffers from vitamin D deficiency, the skin becomes more sensitive and loses its natural moisture. This is especially noticeable in the area of the arms and legs, as well as on the face. And that is exactly the kind of skin that is lifeless and devoid of shine. rash and redness - even itching are also some of the symptoms that occur with an insufficient amount of vitamin D. Apart from being unpleasant, these symptoms also represent an aesthetic problem. The lack of this vitamin makes the skin more sensitive, and skin problems such as psoriasis, eczema or dermatitis occur. acne - is a consequence of hormonal imbalance, and vitamin D deficiency affects the production of sebum in the skin. Sebum is a natural lubricant and is produced by the sebaceous glands, and its role is to preserve the moisture of the skin. However, excessive secretion of sebum leads to clogging of pores, and then to the formation of acne. the skin looks older - in fact, it ages rapidly due to a lack of vitamin D. It is believed to have something to do with the antioxidant properties and preservation of the skin barrier, which is the role of this vitamin. Namely, vitamin D protects the skin from the harmful effects of UV rays, and also stimulates the regeneration of skin cells and contributes to its elasticity, which is a characteristic of young skin. changes in pigmentation - in the absence of vitamin D, pigmentation disorders occur, since this vitamin plays a role in regulating skin pigmentation. Pigmentation disorders, also known as hypopigmentation, manifest as white spots on the skin that stand out from the rest
