If you have diabetes, high blood pressure, heart disease, or a family history of kidney problems, you are at risk for kidney disease. Kidney disease is serious, but if you catch it early, you can slow it down or stop it. Ask your doctor to check your kidneys.
South Asia basically refers to India and the few countries around it. It is known as a subcontinent as it was not originally part of the landmass known as the Asian continent. This can be seen from the presence of the Himalayas.
Whether called the Indian subcontinent or South Asia, the definition of the geographical extent of this region varies. Geopolitically, it had formed the whole territory of Greater India, and it generally comprises the countries of India, Pakistan, and Bangladesh. Prior to 1947, most of the Indian subcontinent was part of British India.
