Underweight can be as bad for your health as being obese. Many people who are not clinically underweight still want to gain some muscle. An underweight person's body mass index (BMI) is less than 18.5 which is not sufficient to lead an optimal health. On the other side, a person whose BMI is over 25 is considered to be overweight and 30 is considered to be obese.
Some people are skinny and healthy. Being underweight according to this scale does not necessarily mean that you have a health problem since BMI scale takes into consideration only weight and height. It does not include muscle mass.
What are the health consequences of being Underweight?
Being underweight can impair immune function, raise your risk of infections, and lead to osteoporosis and fractures, and cause fertility problems. People who are underweight are much more likely to get sarcopenia (age-related muscle wasting) and may be at greater risk of dementia.
Reasons to become Underweight
There are several medical conditions that can result in weight loss.
Here are some of them:
- Eating disorders: This includes anorexia nervosa, a serious mental disorder.
- Thyroid problems: Overactive thyroid (hyperthyroidism) can boost metabolism and results in weight loss.
- Celiac disease: The most severe form of gluten intolerance. Most people with celiac disease don't know that they have it (10).
- Diabetes: Uncontrolled type-1 diabetes can lead to severe weight loss.
