Pain is a general term that describes uncomfortable sensations in the body. It stems from activation of the nervous system. Pain can range from annoying to debilitating, and it can feel like a sharp stabbing or a dull ache. Pain can also be described as throbbing, stinging, sore, and pinching. Pain can be consistent, can start and stop frequently, or can appear only under some conditions. People respond to pain differently. Some people have a high tolerance for pain, while others have a low tolerance. For this reason, pain is highly subjective.
It is, therefore, not surprising that weight loss has become a very topical subject over the years, not only for the obvious cosmetic reasons but also due to increasing awareness of the health risks to people who are overweight. There have been proven links between people being overweight and the development of conditions such as type 2 diabetes, coronary heart disease and stroke as well as some cancers, such as breast and bowel cancer.
