For centuries, physicians have identified many signs in the skin that give clues as to what’s going on inside your body. Some of these signs can indicate that some changes need to be made to your diet or lifestyle while others can indicate serious disease. If you’re noticing changes in your skin, don’t ignore them. Consult with your health professional today.

High Cholesterol

If you’ve noticed yellow patches appearing around your eyes, they could be fatty deposits caused by high cholesterol. High cholesterol puts you at greater risk of cardiovascular disease and should be addressed. It may also be a sign that your liver is under stress or your thyroid is not functioning well – neither of which should be ignored.


If your immune system has mounted a response against something in your environment or diet, it could present on the skin as dry, itchy rashes or swollen and red, itchy welts. Where the rash is occurring and at what time of the day can give you clues as to what you’ve reacted to. Puffiness and/or dark circles under the eyes can also indicate allergies. There are a number of tests available that can identify what you’re allergic to so you can minimise contact and relieve your symptoms.

Thyroid Disease

Your thyroid controls your metabolism and if that’s affected, you may find some signs of it on your skin. Dry, cold skin that has lost its elasticity can indicate the thyroid isn’t functioning well. As can puffiness on waking, swelling around the neck, thickening of the skin on the calves, thinning hair, brittle nails and wounds that are slow to heal. If the thyroid is overactive, it may present as flushing or sweating more than usual or darker patches appearing in the creases of your palms. Thyroid diseases are detectable with a blood test.


If you’re not processing your sugars effectively, some signs may appear on the skin before you’ve been given a diagnosis of diabetes. You may develop thickened red plaques or notice areas of skin – most commonly under the arms and back of the neck – getting darker. This darkening can also be due to other diseases or side effects of medications so it’s worth consulting with your health professional to have it investigated.

Hormone Imbalance

Most of us remember dealing with spots as teenagers but if your acne continues into adulthood and especially if it also occurs with irregular periods, unexplained weight gain or hair in unwanted places, you may want rule out Polycystic Ovarian Syndrome (PCOS). This common condition can affect your fertility and may women find relief with natural therapies.
