The Skinny on Being Underweight: Is It a Concern?

Are you concerned about being underweight? While much attention is placed on the health risks of being overweight, being underweight can also have health consequences.

Learn more about the potential health implications of being underweight, the underlying factors that contribute to this condition and how Medical Weight Management at Inspira at Inspira can help. 

What defines being underweight?

Being underweight is typically defined as having a body mass index (BMI) below 18.5, indicating a weight lower than what is considered healthy for a given height. It's important to note that BMI is just one measure and doesn't account for factors like muscle mass—but it serves as a general guideline for assessing weight status.

What are some potential health implications of being underweight?

“Being underweight can weaken your immune system, making you more susceptible to infections and illnesses,” said Carmen Eberly, A.P.N., a Medical Weight Management nurse practitioner at Inspira Medical Group. “It can also lead to nutritional deficiencies, which can affect energy levels, bone health and even fertility.” Being underweight may also increase your risk of complications during surgery and delay wound healing.

What are some underlying factors that contribute to being underweight?

Several factors can contribute to being underweight, including genetics, metabolism and underlying medical conditions such as thyroid disorders, gastrointestinal diseases or eating disorders like anorexia nervosa. Psychological factors like stress or anxiety can also affect your appetite and contribute to weight loss.

What are some symptoms I might experience if I’m underweight?

Symptoms of being underweight can vary depending on the underlying cause. “Common signs may include fatigue, weakness, dizziness, irregular menstrual cycles and a weakened immune system leading to frequent infections,” said Eberly. “You may also notice changes in your hair, skin and nails due to nutritional deficiencies.”

What can I do if I'm underweight?

Start by talking to your doctor to determine the underlying cause of your low weight and develop a personalized plan, which may involve increasing your calorie intake through nutrient-dense foods, incorporating strength training exercises to build muscle mass and addressing any underlying medical conditions. Your doctor may suggest support from a registered dietitian or joining a medical weight management program for one-on-one guidance and accountability.
