Calcium tablets are mainly supplemented as needed, and some patients may need to take them for a long time. Calcium is very important to the human body and can promote the growth and development of bones. If there is a calcium deficiency, such as calcium deficiency in infants and young children, calcium deficiency in pregnant women, calcium deficiency in the elderly, etc., it is necessary to supplement calcium supplements in a timely manner under the guidance of a doctor, and whether it needs to be taken for a long period of time will depend on the patient’s condition. If the patient has a serious calcium deficiency or suffers from osteoporosis, he/she usually needs to take calcium supplements for a long time according to his/her own condition and follow the doctor’s instruction. However, for infants, young children or pregnant women and other special people, after a period of calcium supplementation to correct the calcium deficiency, the body calcium is sufficient, then do not need to take calcium tablets. If you continue to take calcium tablets for a long period of time, it may lead to excessive calcium intake in the body, which may cause dry stools and stones, and taking calcium tablets for a long period of time may also inhibit the absorption of other nutrients and increase the risk of nutritional deficiencies. It is recommended that if you are deficient in calcium, you should take calcium supplements under the guidance of your doctor and not take them on your own.
