Malnutrition isn't always about dramatic weight loss or extreme hunger. According to a leading dietitian, there are subtle, often overlooked physical signs that someone might be seriously lacking in essential nutrients.
Sophie Medlin, a consultant dietitian and chair of the British Dietetic Association for London, has highlighted the key indicators that someone's body is crying out for better nourishment. These signs can manifest in surprising ways, from changes in your hair and skin to symptoms inside your mouth.
The Tell-Tale Signs On Your Skin, Hair, and Nails
One of the most common places malnutrition shows up is in your outward appearance. Brittle, peeling nails that break easily can be a red flag. Similarly, if your hair is becoming excessively dry, brittle, or even starting to fall out, it could be your body's signal that it's missing vital vitamins and minerals.
Your skin can also tell a story. Unexplained dryness, flakiness, or the development of a rash could be linked to deficiencies in nutrients like zinc, niacin, or essential fatty acids.
Unexpected Symptoms In and Around Your Mouth
Don't ignore what's happening in your mouth. Medlin points out that mouth ulcers and cracks forming at the corners of your lips, known as angular cheilitis, are classic signs of a deficiency—often in B vitamins or iron.
Even your gums can provide clues. Bleeding gums when you brush your teeth might not just be a sign of gingivitis; they can also indicate a lack of vitamin C, a crucial nutrient for maintaining healthy blood vessels and connective tissues.
The Less Visible But Crucial Internal Signs
Beyond what you can see in the mirror, malnutrition affects how you feel. Persistent, overwhelming fatigue that isn't solved by sleep is a major indicator. This is often tied to deficiencies in iron or vitamin B12, which are critical for energy production.
Feeling constantly cold, struggling to concentrate, or experiencing low mood can also be intertwined with poor nutritional intake. In severe cases, nutrient deficiencies can even lead to conditions like osteoporosis or a weakened immune system, making you more susceptible to infections.
Medlin emphasises that noticing these signs in yourself or someone else is a prompt to seek professional help. A GP or a registered dietitian can help identify any deficiencies through simple blood tests and create a tailored plan to restore health through diet and, if necessary, supplementation.
