Ndezvipi zvinokonzeresa ne stem cell therapy?
Stem cell therapy can have a variety of side effects, both short and long term. Fatigue, headache, chills, nausea, and low-grade fever are some of the most prevalent short-term adverse effects. On the other hand, stem cell therapy can cause more serious issues, such as cells’ capacity to travel from implantation sites and convert into inappropriate cell types or multiply, cell failure to function as planned, and tumarara formation. Additionally, stem cell or bone marrow transplants can cause nausea, vomiting, stomach cramps, diarrhea, loss of appetite, jaundice, mouth and throat pain, mucositis, and even secondary malignancies. Individuals considering stem cell therapy should be aware of these potential hazards and seek treatment from reputable facilities that have undergone proper scrutiny and clinical testing.
