Diabetes and Hair loss – is there a link?
Hair loss can affect anyone, including those suffering from diabetes (type 1 or 2). Whether you acquired diabetes through autoimmune causes (Type 1 Diabetes) or through diet and lifestyle (Type 2 Diabetes), you can suffer hair loss from the stress your body is put under from sustained high sugar levels.
There has been a known correlation between Type 1 Diabetes (or any autoimmune condition) and alopecia (hair loss) for a while1. Similarly, if you have acquired type 2 diabetes later on in your life through diet and lifestyle factors, then high sugar levels can also predispose you to hair loss2. But why do high sugar levels affect hair negatively?
The potential link between diabetes and hair loss
We know that high sugar levels put stress on the body’s blood supply of nutrients and oxygen to the organs. Your skin and hair are likewise organs, so naturally, they would also be affected by very high sugar levels. Consequently, hair follicles can go through a process of thinning and can eventually fall out if your sugar levels are too high. Often, patients notice their hair becomes very thin just before they get diagnosed with diabetes.
Additionally, if you have type 1 diabetes (an autoimmune disease), you are also predisposed to alopecia areata. This is also an autoimmune disease whereby your body starts to attack the hair on your head.
In a female, other conditions like Polycystic Ovary Syndrome (PCOS) can also contribute to high sugar levels, and this also worsens hair loss. Together with the high levels of Testosterone in PCOS, you may notice a degree of hair loss.
If you have just been diagnosed with diabetes, it can cause you to feel stressed. This is normal and manageable, but it can also contribute to hair loss.
So, what can you do to control your diabetes and potentially any hair loss?
First things first- you must see your GP and get diagnosed with diabetes appropriately.
Following this, you will be advised on methods to reduce your sugar levels, such as changing your diet and lifestyle. Importantly, try to eat fewer foods containing high amounts of sugar (like doughnuts).
If you have type 1 diabetes, you may also be advised to start insulin. This helps to regulate your sugar level accurately so your body gets the right amount it needs and not too much.7
If you have type 2 diabetes, you should aim to change your diet and lifestyle to reduce your sugar levels.8 If your sugar levels are too high or remain too high despite making these changes, you may start some medication. One of the medications is called metformin.
What is Metformin?
Metformin can be used to reduce your sugar levels. However, as with all medications, there can be side effects. One of the side effects of metformin can include hair loss. This occurs because metformin can reduce your stomach’s absorption of vitamin B12 and can, in the long run, cause anaemia3. This could result in hair loss for some patients4.
What should you do if your sugar levels are under control and you are still losing hair?
If your sugar levels are under control, but you are still noticing hair loss months after being treated for diabetes, then you are likely suffering from a pattern-type hair loss (female or male). You ought to see a hair loss specialist or your GP to find out more, as you will require treatment to prevent hair loss.
There are plenty of treatment options available to you. Minoxidil and finasteride are two great treatment options that can help strengthen your hair and prevent any further hair loss.
If you would like hair back in areas that have none, then a FUE hair transplant could also be an option for you. Our hair loss doctors at The Treatment Rooms London are happy to explore your diagnosis and take you through all the treatments available to you.
