I saw a young patient recently with frequent ulcers on the tongue, and suspected that he may have certain nutritional deficiencies, and on further questioning, he reported that he was a vegetarian. I suggested nutritional testing and replacing vitamins that are often low in a vegetarian diet such as vitamin B12 and iron.
Macronutrients (sufficient protein, fats, and carbohydrates) as well as micronutrients (vitamins and minerals) are needed for optimal bodily functioning. Lack of one or more of these often result in your body trying to compensate for the deficit, often in the functions deemed less crucial for survival.
Our tongues, nails, skin, and hair often reflect our nutritional state.
Hair loss, brittle nails, cracked lips, easy bruising, slow healing of skin wounds, stretch marks, are just some of the signs that you maybe lacking in certain nutrients.
Other common signs of nutritional deficiency are:
Fatigue
Muscle cramps and aches
Tingling sensation or numbness
Loss of bone density
Headaches/migraines
Irregular heart rate
Cold hands and feet
Gastrointestinal symptoms
Mood and sleep disturbances
Frequent infections
Who is at risk of nutritional deficiency?
Although almost anyone can suffer from nutritional deficiency if you don't eat a varied diet, there are certain groups of people that are more at risk.
Picky eaters (e.g. children)
Elderly - often have poor appetite and do not eat sufficient protein
Vegetarians & vegans
People with cancer
People who have certain underlying medical conditions or undergoing treatment
What should I do if I suspect I have nutritional deficiency?
The first step is to see a doctor or health practitioner who is well versed in nutrition. They will usually ask you about your symptoms and dietary history, and perform a physical examination.
Blood tests can be done to determine if there is any nutritional deficiency. Your integrative health practitioner will then work with you to come up with a treatment plan to restore your nutrient levels, and maintain them at at an optimal level.
Restoring your key nutrients to the proper levels are the first step in healing. Trying to target other bodily systems such as hormones, gut, or mood - when your body does not have the basic building blocks to function - is like trying to build a skyscraper with miniature bricks.
