There is no clinical statement of the top ten signs of immune deficiency. Usually, people with immune deficiency are prone to generalized weakness, gastrointestinal discomfort, and recurrent infections. There are many signs of immune deficiency, not necessarily the top ten signs. Clinically, the common signs of immunocompromised people include generalized fatigue, mostly manifested as shortness of breath after activity, palpitations (accelerated heartbeat, often accompanied by panic), limb pain, etc. Some immunocompromised people are also prone to generalized fatigue. Some immunocompromised people are also prone to gastrointestinal symptoms, such as diarrhea, abdominal pain, bloating, etc., which can have a certain impact on their lives. In addition to the above, people with reduced immunity are also prone to recurrent infections, such as respiratory tract infections, oral infections, skin infections, etc., which are mainly related to the reduced ability of the body to resist external pathogens and harmful substances. At the same time, people who are already sick can also suffer from the phenomenon of prolonged illness due to decreased immunity, which should be taken seriously. For people with reduced immunity, they can take medication as prescribed by the doctor, such as static injection of human immunoglobulin, etc. They should also do physical exercise, such as running, slow walking, yoga and so on. Pay attention to consume more fresh vegetables, fruits, meat and eggs, such as apples, bananas, eggs, lean meat, etc., which can help supplement the nutrients needed by the body. If you find that the immune system is declining, it is recommended that you consult a doctor in a timely manner and follow the doctor’s instructions for standardized diagnosis and treatment if necessary.
