Most of the kidney diseases are a group of immune diseases. Long-term proteinuria as well as immunosuppressant treatments make kidney patients with low immune function and weakened ability to resist external evils. Although chronic kidney disease patients are most avoided to suffer from colds, as a result, they are most prone to colds. What should I do when I have a cold and fever? In fact, common cold is not scary, and only mild cold symptoms can be avoided by taking medicine, drinking more water, resting and keeping warm. For some patients with cold, tiredness or fatigue, you can drink more water or boil some ginger soup (shredded ginger, a small amount of brown sugar + water) to increase the detoxification of the kidneys and the body’s ability to drive away the cold, and of course, you can also use some mild Chinese medicines for a short period of time to alleviate the symptoms, and do not use Chinese medicines with unknown or unidentified ingredients (some Western medicines are suspected to contain antipyretic and analgesic drugs). Common viral colds can be relieved in a week or so. If the course of the disease extends to more than a week, or the disease is gradually progressing and accompanied by bacterial infections, you can consider the use of antibiotics as prescribed by the doctor, in the process of medication should increase the amount of water to increase the amount of excretion of the kidneys, to reduce the chances of drug-related kidney injury. For patients who are using immunosuppressive drugs, their dosage can be appropriately reduced or discontinued during a cold, such as: cyclophosphamide, enzyme phenolate, tacrolimus, etc., while prednisone is not recommended to stop abruptly. For those who are used to exercise, it is not recommended to continue to exercise during cold and flu, but at most to walk lightly and slowly. For those who are physically weak and have frequent colds, it is recommended to start effective exercise within two to three weeks after the cold subsides to strengthen the body to improve immunity to colds. The following measures can be taken: 1. Carry out some physical exercises that are within your ability, such as brisk walking, taking a walk, playing tai chi, doing radio exercises, practicing qigong, yoga, etc. 2. 2, pay attention to environmental and personal hygiene, go out with a mask, to avoid morbidity triggers. 3, pay attention to climate change, add clothes at any time to prevent cold and cold.
