1, diet: control the structure of the diet, to avoid excessive intake of acid. Most vegetables and fruits are alkaline foods, while most meat, grains, sugar, wine, fish and shrimp are acidic foods. The normal environment of the human body is weakly alkaline, that is, when the PH value of body fluids is maintained between 7.35 and 7.45, it is healthy. However, because of the influence of diet, living habits, surroundings and emotions, human body fluids often tend to be acidic, and out of instinct, in order to maintain the acid-base balance of body fluids, the body will use alkaline substances in the body to neutralize these acids. The most abundant alkaline substance in the body is calcium, which is present in large quantities in the bones. Then, when eating a lot of acidic food, the body will naturally consume the calcium in the bones to neutralize the acidity of the blood to maintain the acid-base balance. The elderly are prone to osteoporosis, and some people have been taking calcium supplements for several years, but they still have osteoporosis, which is the result of an acidic body. So the acidic body wants to supplement calcium, must first correct acid, improve the acidic body, calcium can be successful. In addition, smoking will affect the formation of bone peaks, excessive alcohol consumption is not conducive to bone metabolism, drinking strong coffee can increase urinary calcium excretion, affecting the body’s absorption of calcium, excessive salt intake and excessive protein will also increase calcium loss. You should avoid these bad habits in your daily life. Preventing calcium deficiency also requires good lifestyle habits. Karaoke all night, mahjong, sleepless nights, and other irregularities in life can aggravate the acidification of the body. You should develop good habits to maintain a weak alkaline body and prevent osteoporosis. Maintain a good mood, do not have excessive psychological stress, too much stress can lead to the deposition of acid, affecting the normal conduct of metabolism. Proper regulation of mood and their own stress can maintain a weak alkaline body, thereby preventing the occurrence of osteoporosis. 2, exercise: exercise can promote the body’s metabolism. Outdoor exercise and receive the right amount of sunlight, are conducive to the absorption of calcium. Exercise muscle contraction, direct action on the bone pull, will help increase bone density. Therefore, proper exercise is also beneficial for the prevention of osteoporosis. Some studies have found that elderly people who regularly participate in sports have particularly good balance and higher bone density in their bodies than those who do not exercise at the same age; and they are less likely to fall, which may effectively prevent the occurrence of fractures. The more meaningful exercise methods for osteoporosis are walking, playing tai chi, doing various exercise drills, and swimming exercise if possible, for half an hour or more a day. Sunbathing and sports exercise first for a short time, and then slowly increase and extend the exercise time. 3, basic calcium treatment: oral calcium + vitamin D: the simpler and easier way is to take oral calcium D, each tablet contains the main ingredient calcium carbonate 1.5 grams (equivalent to 600 mg of calcium), vitamin D 125 international units. Take 1 tablet once, 1-2 times a day. If taken twice a day, it should be taken once in the morning and once in the evening, and then at night before bedtime. 4, treatment of osteoporosis (the following drugs need to be combined with calcium and vitamin D): bisphosphonates: can inhibit bone resorption, one of the most widely used anti-osteoporosis drugs. The most commonly used ones are Fosamax (imported) and Gubang (domestic). One tablet of 70 mg, one tablet per week. It should only be used on the morning of a fixed day of the week. To deliver the drug to the stomach as soon as possible and reduce irritation to the esophagus, it should be taken early in the morning with a full glass of plain water, and avoid lying down for at least 30 minutes after taking the drug. In addition, in recent years, there are injections of bisphosphonates available under the trade name of MIGUDA (imported), 100 ml/pc. Only one intravenous drip per year is needed to inhibit bone resorption for one year. Calcitonin: It can inhibit bone resorption and promote bone formation. It is suitable for those who have severe osteoporosis with bone pain. There are two kinds of calcitonin: salmon calcitonin and eel calcitonin, which can be injected subcutaneously or intramuscularly, and also nasal spray. Eel calcitonin is given subcutaneously or intramuscularly, 20iu/shot, 1 shot/time, 2 times/week. Salmon calcitonin, 50iu/stick, 1 stick/dose, 1 time/day. Salmon calcitonin nasal spray, 28 sprays/spray, 2 sprays/day (one spray per nostril). Selective estrogen receptor modulators: Selective estrogen receptor modulators with selective agonistic or antagonistic activity on estrogen-acting tissues. Significantly reduces the incidence of vertebral fractures and prevents and treats postmenopausal osteoporosis. It can be taken orally at any time of the day and is not restricted by meals. No dose adjustment is required in the elderly. Long-term use is required due to the natural course of the disease.
