Most people know that being overweight can lead to a number of health problems, but what they may not know is that being underweight can also be dangerous. In fact, being underweight can actually be just as harmful to your health as being obese.

There are a number of different health risks associated with being underweight, including:


Anemia is a condition in which the blood has a low level of red blood cells. This can lead to fatigue, shortness of breath, and an increased risk of infections.

Bone loss

Being underweight can lead to a condition called osteoporosis, which is a deterioration of the bones. This can make them brittle and more likely to break.

Growth problems

Children who are underweight may not grow and develop properly. They may also have delayed pubertal development.

Immune system problems

People who are underweight are more susceptible to colds, flu, and other infections. This is because the immune system is not as strong in people who are underweight.


Malnutrition is a condition that occurs when the body does not get enough nutrients. This can lead to a number of problems, including muscle weakness, hair loss, and problems with wound healing.

How can I gain weight?

If you are underweight, there are a number of things you can do to gain weight. These include:

Eating more calories

You need to consume more calories than your body burns in order to gain weight. This means eating more food, including snacks and dessert. You can also try drinking smoothies or shakes made with high-calorie ingredients such as peanut butter or ice cream.

Increasing your protein intake

Protein is essential for muscle growth. If you are trying to gain weight, you should make sure that you are getting enough protein in your diet. Good sources of protein include meat, poultry, fish, beans, and nuts.

Adding healthy fats to your diet

Healthy fats can help you gain weight. Good sources of healthy fats include avocados, olive oil, and nuts.

Increasing your calorie density

You can also increase the number of calories you consume by increasing the calorie density of your meals. This means adding more high-calorie ingredients such as cheese, peanut butter, or cream to your meals.

How fast should I gain weight?

If you are underweight, you should aim to gain about 1-2 pounds per week. This may seem like a slow process, but it is important to gain weight slowly so that your body has time to adjust. Gaining weight too quickly can lead to health problems such as stretch marks or obesity.


Being underweight is associated with a number of different health risks. If you are underweight, you should talk to your doctor about ways to gain weight safely. You should also make sure that you are getting enough calories and protein in your diet. Gaining weight slowly (about 1-2 pounds per week) is the best way to avoid health problems associated with being underweight.
