Our skin is more than just a protective barrier. It is, in fact, the mirror of our internal health. One of the most common causes that affects the skin is high blood sugar, especially in people suffering from diabetes or those who are prone to insulin resistance. However, how does exactly high blood sugar affect your skin? Let's dive into the science with Dr Vedant Ghuse- a leading dermatologist in Chembur, to help establish how glycemic levels are tied to skin health.
Blood sugar or glucose is an important source for the production of energy, but when it is elevated over time, it can lead to several skin problems because physiological changes caused by high blood sugar can interfere with normal skin function and appearance.
Glycation is one of the most significant processes that links hyperglycemia with dermal damage. It occurs as free glucose in the bloodstream binds to proteins such as collagen, elastin, and fats, causing another molecule, advanced glycation end product, or AGE, to form.
These AGEs interfere with the normal function of proteins in the skin, causing decreased elasticity and strength. Collagen and elastin are responsible for firming up and plumping of the skin, which makes it look soft and young. When these proteins get damaged, the skin cannot regenerate itself properly, causing it to sag, wrinkle, and grow dull.
High sugar levels in the blood also make people susceptible to dry skin. When there is excess sugar in the system, the kidneys often respond by producing more liquid to flush it out. Loss of fluid through excessive urination can dry up the skin and exacerbate irritation, flakiness, and roughness of the skin. Dry skin will then cause other associated issues like itching, eczema, and fungal infections.
Further, it interferes with the production of healthy oils in the body, which are found necessary to sustain hydration and also prevent damage from environmental stressors to the skin. Consequently, the skin becomes vulnerable.
Although less frequently recognised as an acne trigger, high blood sugar is also linked to acne. High blood sugar usually affects the body by causing insulin resistance which can stimulate the production of sebum and promote inflammation. These factors can lead to clogged pores and encourage the development of acne.
Apart from the signs and symptoms mentioned, Dr Vedant Ghuse- a trusted skin specialist in Chembur mentions that hyperglycemia also negatively affects any underlying skin conditions, including acne rosacea and psoriasis. The chronic inflammation present in both hyperglycemia and skin conditions makes the skin more reactive and prone to flare-ups.
High blood sugar has a tendency to cause hyperpigmentation, which refers to dark spots. Insulin resistance and high glucose cause a rise in the production of melanin on the skin, with improper times of uniformity in colour and appearance. This largely manifests on parts such as the neck, underarms and elbows due to the accumulation of folds of the skin rubbing against each other.
Maintaining healthy blood sugar levels is important not only for your general health but also for the development and maintenance of healthy, vibrant, and youthful-looking skin. Most skin problems caused by high blood sugar can be avoided through proper diet, moderate exercise, and ideally correct medication.
