Fever is one of the most common health ailments that affects people from time to time. Also known as pyrexia or controlled hyperthermia, it is medically defined as a condition in which the body temperature rises above the nominal levels of 98-99° Fahrenheit (36-37° Celsius). It is typically recognized as a potential sign that something unusual is happening in the body.
Medical experts assert that fever or elevated body temperature is generally caused by overexposure of the skin to sunlight, dehydration, viral or bacterial infections, heat exhaustion, or inflammatory conditions like rheumatoid arthritis. It could also arise as a side-effect of certain medications like antibiotics and some drugs used in the treatment of hypertension or seizures. Furthermore, it can evince certain symptoms like shivering, lack of appetite, lethargy, and sweating.
There are various types of fever that can make life difficult for the people. Though some minor conditions can be treated easily with medications and pharma products manufactured by the top pharmaceutical companies in India, others can be more serious and may require immediate medical attention.
