Do you often feel EMO (short for emotional, representing an emotion, meaning depression, negativity, and restlessness)? Recently, the reporter noticed that many netizens have found the reason for their EMO, which is actually related to a lack of vitamin D in the body. Director Lu Lijuan from the Pain Department of Nanjing Gulou Hospital pointed out that a lack of vitamin D can indeed lead to various sub health conditions, but it is not recommended to blindly supplement just because of a "bad mood". Unexpectedly, there is a lack of vitamin D, and many netizens have found the reason for EMO. Ms. Yao (surnamed Hua) posted that she has been prone to EMO and sensitive since a long time ago, and even if things are going smoothly, she will suddenly feel down. Sleep for 9 hours a day and the quality of sleep is not bad, but the next day it is still difficult to feel drowsy, especially on cloudy and rainy days. Ms. Yao has also tried the "coffee+exercise" approach, but she feels that it can only be alleviated, occasionally accompanied by symptoms of low back pain. After posting on Xiaohongshu, Xiaohongshu's' expert consultation 'suggested that I check for vitamin D, so I went straight to the hospital for testing, but it turned out that I really lacked vitamin D. "Netizen" Xiaoju "wrote that she started to worry because she had a cold for a long time, and later turned into crying every day," going crazy ", and not being alone in the room, otherwise she would have chest tightness, shortness of breath, and panic, thinking she had anxiety disorder. Occasionally brushing for a lack of vitamin D can also cause fatigue and EMO, and then I went for an examination. As expected, I was lacking too much. "The examination report released by" Xiaoju "showed that her vitamin D test value was only 16.47ng/mL. There is a clear quantitative standard for whether vitamin D is lacking. The normal value of vitamin D should be greater than 30ng/mL, 20-30ng/mL is insufficient vitamin D, while below 20ng/mL, it should be noted that it is already in a state of vitamin D deficiency. This also means that the vitamin D value of 'Little Orange' is only half of the normal value. After three months of supplementation, "Xiaoju" updated its post again. This time, she said she has returned to her original mood. "Every day, she is full of energy, cooking, exercising, shopping, chatting with friends, and going out to bask in the sun for a while. Her mood is super good." "In clinical practice, we often encounter patients like this, who are all uncomfortable and cannot detect any diseases, but the results show a lack of vitamin D." Lu Lijuan, the chief physician of the pain department at Nanjing Gulou Hospital, introduced in an interview with reporters, Lack of vitamin D can indeed lead to various sub health states. Vitamin D is a fat soluble vitamin, mainly formed by ultraviolet radiation on cholesterol in subcutaneous tissue. It has the function of regulating calcium and phosphorus metabolism in the body, promoting calcium absorption and utilization, and forming healthy bones and teeth. It is generally recognized that vitamin D deficiency can lead to osteoporosis in the elderly, but it is also closely related to chronic pain and other basic factors. Scientific research has confirmed that vitamin D deficiency exists in a considerable part of patients with rheumatoid arthritis, heart disease, diabetes, anxiety, depression, cancer and other diseases.
