What problems can being underweight cause?

People who are underweight typically are not getting enough calories to fuel their bodies. Often, they are also suffering from malnutrition, since they aren’t taking in enough vitamins and minerals from their food. If you’re underweight, you may be at risk for the following health issues:



Inhibited growth and development.
This is especially true in children and teens, whose bodies need plenty of nutrients to grow and stay healthy.



Fragile bones.
A deficiency in vitamin D and calcium along with low body weight can lead to weak bones and osteoporosis.



Weakened immune system.
When you don’t take in enough nutrients, your body cannot store energy and may also have difficulty fighting illness. It may also be difficult for your immune system to bounce back after being sick.



Anemia.
This condition can be caused by iron deficiency, folate deficiency and vitamin B12 deficiency, resulting in dizziness, fatigue and headaches.



Fertility issues. In women, low body weight can lead to irregular periods, lack of periods and infertility.



Hair loss.
Low body weight can cause hair to thin and fall out easily. It can also cause dry, thin skin and teeth health issues
