Weight (WT) is a body vital sign that reflects a person's health and well-being. It comprises different components, including fat mass and lean body mass, which consists mostly of muscle tissue.
If you are overweight or obese, you are at higher risk of developing serious health problems, including heart disease, high blood pressure, type 2 diabetes, gallstones, breathing problems, and certain cancers.
Your body weight can regularly fluctuate. But the persistent, unintentional loss of more than 5 per cent of your weight over 6 to 12 months is usually a cause for concern. Losing this much weight can be a sign of malnutrition.
