Vitamin D is a fat-soluble vitamin that is synthesized in your skin during sun exposure. Vitamin D helps in the absorption and utilization of calcium to keep bones and connective tissues strong. Vitamin D's effect on bone and joint health may be the very reason a lack of vitamin D can contribute to musculoskeletal pain. The shoulder is a common site for chronic pain, and vitamin D may benefit those suffering from painful shoulders.
Chronic Shoulder Pain
肩膀是由一个复杂的组合啊f nerves, muscles, tendons and joint tissues. All of these tissues work together to help you throw a ball, scratch your back or lift a fork. Most shoulder pain is caused by tendon inflammation and arthritis in the shoulder joints, resulting in chronic shoulder pain and inflammation. In 2009, Mayo Clinic research revealed that patients with chronic pain had low levels of vitamin D and needed nearly twice the amount of narcotic pain-relievers as those with normal levels. More research is needed, but some physicians are already testing patients with musculoskeletal pain for low vitamin D levels.
Osteoporosis and Arthritis
Three bones form the shoulder, including the upper arm bone, the shoulder blade and the collar bone. Osteoporosis is a disease that causes thinning of the bone tissue and can affect the shoulder bones, resulting in bone pain and an increased risk for fractures. Vitamin D increases calcium absorption, thereby preventing osteoporosis. Autoimmune diseases like lupus and rheumatoid arthritis are caused by an overactive immune system that attacks the body's connective tissues, resulting in shoulder pain and inflammation. Besides helping with chronic pain, vitamin D is a potent immune system modulator that helps normalize certain cells and enzymes that fuel joint inflammation in autoimmune diseases.
补充
Vitamin D offers many health benefits, but you must know how much vitamin D you need. In 2010, the Food and Nutrition Board, or FNB, established a recommended daily allowance of vitamin D to maintain bone and joint health without reaching vitamin toxicity. Vitamin D is best acquired through skin contact with direct sunlight for 5 to 30 minutes twice a week, but some people do not get enough sunlight to maintain adequate levels and few foods contain enough of the vitamin to be therapeutic. Based on minimal sun exposure, the FNB suggests 600 IU daily for adults, but some doctors feel higher levels are needed. Ask your doctor for a vitamin D blood test to see what amount of vitamin D is right for you.
Contraindications
过量的维生素d可引起消瘦,心脏心律失常,增加排尿。最大的风险是钙在血液中一个危险的堆积,造成肾结石,血管损伤和心脏肌肉损伤。此外,维生素d可能不利于某些种类的肩部疼痛,包括神经损伤,椎间盘突出或肩关节不稳痛苦,所以找医生确诊服用维生素D.一如既往之前,最好向医生有关治疗方案的疼痛和维生素d补充。
