Underweight or Malnourishment

Being underweight or malnourished is defined as having a BMI of  less than 18.5. You may be underweight for a variety of reasons:

  • Stressful life event
  • Recovering or battling an illness
  • Underlying disease
  • Lack of interest in food

If you are losing weight without any obvious reason, it is a good idea to check in with your GP to have your bloods taken and ensure that there is no underlying disease. The main symptoms of being underweight or malnourished are: 

  • Lack of energy
  • Fatigue
  • Poor appetite
  • Reduced immunity
  • Slow healing cuts and bruises

However, not everyone has the same symptoms and some people may not have any symptoms. If you are underweight, it is advisable to see a Dietitian as long-term consequences include:

  • Nutritional deficiency - lacking essential nutrients
  • Reduced immunity - causing susceptibility to illness
  • May affect mental health - the individual may be more likely to experience low moods
  • Disease - e.g. osteoporosis in the long-term


What should you do if you think you are underweight or malnourished?

If you suspect that you are at risk, you should speak with your GP to take blood tests to ensure that there is no underlying disease or nutritional deficiencies. Booking an appointment with a Dietitian will be your next step. A Dietitian can help you to optimise your diet and lifestyle to gain weight in a healthy and realistic way for you.
