Diabetes is a chronic disease that affects how the body processes blood sugar. Uncontrolled high blood sugar can cause damage to blood vessels and nerves over time, which can lead to complications that prematurely age the body. So do diabetics tend to look older than their peers without diabetes? Let’s take a closer look at the evidence.
The effects of diabetes on physical appearance
There are several ways that poorly controlled diabetes may accelerate visible signs of aging on the body:
- Skin damage – High blood sugar causes glycation, which is when sugar molecules attach to proteins. This process damages collagen and elastin, proteins that keep skin firm and elastic. Over time, skin can become thicker, less elastic and more prone to wrinkles.
- Hair loss – Diabetes can cause restricted blood flow and nerve damage to hair follicles, leading to thinning hair or balding patches.
- Weight fluctuation – The inability to properly metabolize sugar can lead to unintentional weight loss or gain. These fluctuations in weight can lead to a more aged appearance.
- Vision issues – High blood sugar damages blood vessels in the eyes, leading to retinopathy, cataracts and vision loss. Vision changes may alter facial expressions.
- Dental problems – Gum disease and tooth loss are more common in diabetics, which can lead to sunken cheeks or missing teeth that give the appearance of aging.
- Skin discoloration – Some diabetics develop skin tags, dark velvety patches (acanthosis nigricans), or reddish scaly patches (necrobiosis lipoidica diabeticorum) which can add years to appearance.
In essence, the circulatory and nervous system damage caused by chronically high blood sugar can accelerate many common visible signs of aging. However, the progression depends greatly on how well diabetes is managed.
How does diabetes management impact aging?
The progression of diabetes complications depends heavily on blood sugar control. Diabetics who carefully manage their condition may not necessarily appear older than their actual age. Here’s an overview:
- HbA1c level – This blood test measures average blood sugar over 2-3 months. Diabetics with well-controlled HbA1c (less than 7%) typically have minimal visible aging from diabetes.
- Medication compliance – Taking medications as prescribed and monitoring blood sugar levels can dramatically slow the onset of diabetes complications.
- Diet – Eating a nutritious, diabetes-friendly diet can help maintain healthy weight and blood sugar levels.
- Exercise – Regular physical activity aids blood sugar control and reduces risks associated with diabetes.
- Lifestyle factors – Avoiding smoking and sun damage helps minimize non-diabetes related skin aging.
- Care of complications – Proper wound care, treatment of infections, and eye exams can prevent many visible complications.
In contrast, those with poorly controlled diabetes who do not take steps to manage their condition are more likely to develop visible symptoms of premature aging. This includes advanced skin wrinkling, hair loss, skin disorders, weight loss/gain, vision issues and dental problems.
Major studies on diabetes and aging
Several major scientific studies have investigated the connection between diabetes and premature aging:
- A 2020 study published in Diabetes Care followed over 2,000 middle-aged diabetics for 18 years. They found those with poorly controlled blood sugar aged significantly faster based on photographs. Average excess aging was 4.8 years.
- A 2010 study in the Journal of Gerontology compared diabetics and non-diabetics over age 70. Those with diabetes showed markedly more visible aging signs, including wrinkled skin and balding. The effects were more pronounced in those with longer disease duration.
- A 2008 Danish study published in Experimental Gerontology looked at aging markers. Diabetics had shorter telomeres, which are protective caps on DNA strands that shorten with age. Shorter telomeres correlated to prematurely aged skin and hair.
- A 1999 study in the Journal of the American Geriatrics Society found diabetics as young as 30 displayed clinical markers of advanced aging like bone density loss and arterial stiffening typical of those much older.
Overall, multiple large studies demonstrate strong links between diabetes, blood sugar control, and visible aging signs like wrinkled or inelastic skin. While results depend greatly on individual disease management, on average diabetics do tend to appear older than non-diabetics of the same chronological age.
Ways diabetics can slow visible aging
While diabetes can accelerate aging markers, there are steps diabetics can take to look more vibrant and youthful:
- Control blood sugar – Work with your doctor to keep HbA1c levels in target range.
- Quit smoking – Cigarettes worsen diabetes complications and rapidly age skin.
- Exercise regularly – Activity aids blood sugar regulation and boosts circulation.
- Moisturize skin – Use rich, nourishing creams to hydrate skin and reduce wrinkles.
- Use sunscreen – Protect skin from UV damage to minimize wrinkles and sun spots.
- Eat nutritiously – Focus on produce, lean proteins and whole grains to maintain healthy weight.
- Do strength training – Building muscle tone helps skin appear firmer and more youthful.
- Consider cosmetic options – Botox, fillers, laser treatments can minimize visible aging signs.
While living with diabetes poses skincare challenges, looking vibrant and healthy at any age is certainly achievable. Work closely with your healthcare provider for the best diabetes management plan.
Conclusion
Research clearly shows a link between diabetes and accelerated visible aging, especially in those with poorly controlled blood sugar. However, diligent disease management can dramatically slow the onset of aging side effects. Diabetics who monitor blood sugar, take medication as prescribed, exercise and eat nutritiously can maintain a youthful appearance longer. Some visible aging is inevitable with age, but proper diabetes care allows many diabetics to look as young and healthy as their non-diabetic peers.
