Barium sulfate is often used as a contrast agent during X-ray examinations to help doctors observe internal structures such as the digestive system and cardiovascular system. Although barium sulfate is usually not harmful to the human body, it may cause allergic reactions or other adverse reactions in rare cases. Specifically:
1. Allergic reactions: In the process of clinical application of barium sulfate, we found that a small number of people may have allergic reactions to barium sulfate. This allergic reaction can take many forms, including skin flushing, that is, the patient's skin will suddenly become extremely ruddy, as if it has been stimulated by some kind; shortness of breath, that is, the patient's breathing rate will be significantly accelerated, sometimes accompanied by wheezing, giving people an intuitive feeling of dyspnea; there may also be rashes, which may be small red spots, plaques or other shapes, they can appear on the surface of the patient's skin, causing discomfort and distress to the patient. Although these allergic symptoms are not common, once they occur, corresponding medical measures need to be taken immediately to ensure the safety and health of patients.
2. In terms of other adverse reactions, special attention should be paid to the fact that when barium sulfate is accidentally ingested into the digestive tract, it may cause a series of discomfort symptoms. Specifically, it may cause constipation in patients, make defecation difficult and irregular, and bring unnecessary distress and pain to patients. In addition, barium sulfate may also cause diarrhea, which increases the frequency of defecation and thin stool. In severe cases, it may even be accompanied by symptoms such as abdominal pain and bloating. The appearance of these symptoms will have a certain impact on the daily life and health of patients. Therefore, when using barium sulfate or related products, you need to be extra careful to avoid unnecessary intake and accidental ingestion.
Barium sulfate is usually not absorbed by the body and is excreted through defecation. However, before using barium sulfate contrast, doctors evaluate the patient's condition to make sure there are no allergic reactions or other contraindications. After receiving barium sulfate contrast examination, patients should drink plenty of water to promote the excretion of barium.
