If you are a diabetic patient, you are at a bigger risk of having sores and ulcers. There are several reasons why Diabetic patients suffer from sores and ulcers. Read this blog to know about diabetic ulcers and sores.
Ulcers are referred to as open sores on the skin that do not heal in the way they should. Very often, it occurs on the hands and legs, but it can also occur on other parts of the body like the stomach.
One of the main reasons why Diabetic patients suffer from ulcers and sores are high blood sugar levels as it damages the nerves and blood vessels. It lessens the blood flow especially in the hands, feet, and limbs which makes it harder for the sores to heal, making the body prone to other infections too.
In many cases, Diabetes leads to a condition known as Peripheral Arterial Disease (PAD) which reduces the flow of blood in the legs and feet. As the nerves get damaged, it becomes harder for a person to feel the pain or other symptoms of ulcers.
Ulcers are dangerous as they can lead to serious infections and in some cases, they can also cause Gangrene, a condition in which the tissue dies.
Diabetic ulcers are the open sores on the skin which usually occur on the hands and legs. The main cause of this complication is high amounts of sugar in the bloodstream of the patient. This damages the nerves and blood vessels in the legs and hands resulting in inadequate blood flow to the parts. It may cause serious infection and hence, it is highly recommended to see a doctor if you notice any unusual thing on your skin.
Diabetic Ulcer Symptoms
The first sign of foot ulcers that patients face is drainage coming out of your foot, which is noticed in the form of sock strain or in the shoes. Here are a few more symptoms you may notice early in the disease –
- Unusual swelling
- Odour from one or both feet
If the problem has already gotten serious, the most visible sign is black tissue, also known as eschar, around the ulcer. It happens because there is not a healthy blood flow around the area surrounding the ulcer.
You can also see partial or complete gangrene, which means that the tissue around the ulcer has died owing to the infection. It results in odorous discharge and pain from the ulcer and can also cause numbness.
Foot ulcer symptoms are not always evident as sometimes, you may not see a single sign of it till it gets infected.
You should stay in constant touch with your doctor and report if there is any skin discoloration, like tissue has turned black, or feel some sort of pain around the area which looks callused or irritated.
The normal symptoms of dibetic ulcers include unusual swelling, odour from one of both feet, redness and irritation, but there can be more severe symptoms as well, like black tissue, gangrene and complete numbness.
