5 warning signs of vitamin D deficiency that are often overlooked

Vitamin D, often called the ‘sunshine vitamin’, is an essential nutrient that plays a crucial role in bone health, immune function, and overall well-being. Despite its importance, approximately 1 billion people struggle with vitamin D deficiency globally. In some populations, the deficiency rate is almost 50%. When there is a nutrient deficiency, your body gives signals. Catching the early signs and symptoms of vitamin D deficiency is crucial to prevent conditions such as hypocalcemia, secondary hyperparathyroidism, soft bones, osteoporosis, and risk of bone fractures. Here are five warning signs of vitamin D deficiency that you should not ignore.Feeling tired One of the crucial signs of vitamin D deficiency is fatigue. One may feel tired constantly, even after adequate rest. Vitamin D plays a crucial role in energy production and muscle function. When the levels drop, the body struggles to convert food into energy, leading to fatigue. If you feel tired after a good night’s sleep, and it persists, it is important to consult a doctor. Studies have consistently shown the link between low vitamin D and fatigue.Frequent illnessLack of vitamin D or low levels of vitamin D can weaken the immune system. This could lead to frequent illness. People with low vitamin D levels experience frequent colds, flu, or other infections. Frequent health issues should not be ignored at any cost. Studies have also shown that vitamin D deficiency can lead to respiratory tract infections, such as the common cold, bronchitis, and pneumonia. If you are catching every bug going around, it is important to talk to your doctor. Muscle weakness or painAnother hallmark sign of low vitamin D levels in the body is muscle weakness or pain. If the muscle weakness or pain is unexplained, it is a cause of concern. Vitamin D plays a crucial role in muscle function, and deficiency may lead to discomfort or reduced strength. People often mistake this for overexertion or aging. A 2018 review found that low vitamin D levels were linked to arthritis, muscle pain, and chronic widespread pain. This pain could be either mild or severe, and sometimes can impact daily activities.Mood changesYes, low vitamin D levels can lead to mood changes. Do you find yourself feeling down, anxious, or irritable often? Well, then it's time to check your vitamin D levels. Vitamin D influences serotonin production, a neurotransmitter responsible for mood regulation. A deficiency can lead to increased risks of depression and anxiety. Studies also confirm that low vitamin D concentration is associated with depression. Bone pain Vitamin D deficiency can also cause bone pain. This happens because low vitamin D levels reduce calcium absorption, which is essential for bone strength. Without adequate vitamin D, the bones would become weak, soft, and more prone to pain and fractures. It can also lead to conditions like osteomalacia, causing bone pain, muscle weakness, and an increased risk of fractures. This sign can get overlooked, but it is important to consult your doctor if the pain persists.
