The question I get asked the most about is: “what are the most common vitamin D deficiency symptoms?” And my answer is expanded into this article you’re reading now. Enjoy and tell others about it! Vitamin D Deficiency Symptoms: Hand or Foot Spasms Hand or foot spasms is a vitamin D deficiency symptom that may be often overlooked when symptoms are milder. However, these muscle spasms may cause a strong discomfort to individuals with more severe vitamin D deficiencies. Cramps can happen in any part of the body where there's muscle. When cramps occur in hands or feet, they usually are sudden and develop quickly. The discomfort level can range from a mild irritating tingle to an extremely painful spasm. Hand or foot spasms may have several symptoms such as fatigue, cramping, muscle weakness, twitching, numbness, tingling, and uncontrolled rapid muscle movements. These spasms are involuntary contractions of muscles and the muscle cramping may be visibly seen as a bulge under the skin and hard when touched. For some individuals, they may feel cramps after working out or exercising. These muscle contractions may be caused by a deficiency in vitamin D. Vitamin D Deficiency Symptoms in Women: Depression A few studies show that inadequate vitamin D levels may increase the risk of developing depression. Vitamin D facilitates in the production of serotonin, a neurotransmitter that is related to our mood. Women with lower serotonin levels have mood disorder symptoms such as Major depressive disorder (MDD) and seasonal affective disorder (SAD). Researchers have found that women who live in northern latitudes and use lots of sun screen may not be getting enough sun exposure. The amount of sun is also limited in the winter months. When sun rays are limited, the skin is not able to synthesize enough vitamin D and this may lead to vitamin D deficiency symptoms. Vitamin D Deficiency Symptoms Fatigue Fatigue is generally the most common of all the symptoms. There is a really big chance that if you do not deal with this issue very quickly you may start to experience more problems within a very short time. Usually when you hear someone talking of fatigue, you may even ignore that issue but in relation to the deficiency the fatigue cannot be ignored because it is very serious. The fatigue involved here is that which makes you very weak, even to the point that you cannot do the normal daily chores that do not require a lot of effort to complete.
