Diabetes and Wound Healing – Why is it Slower?

TAMPA, Fla. - Jan. 16, 2025 - PRLog -- But why does the diabetic wound healing process take longer?

In this article, we will explore the connection between diabetes and delayed wound healing, discover the reasons behind it, and share tips to promote recovery.

How does diabetes affect wound healing?

Diabetes is the result of your body's inability to produce insulin. Insulin is responsible for metabolizing sugar or glucose and turning it into energy. When your body cannot carry out this process naturally, it causes an increase in blood sugar levels, which affects your body's natural healing process in the following ways:

• Poor blood flow: High blood sugar can damage blood vessels, reducing the flow of oxygen and nutrients to the wound. These are essential for healing.
• Weakened immune system: Diabetes makes it harder for the body to fight off infections, which can slow healing and make wounds worse.
• Nerve damage: Over time, high blood sugar can cause nerve damage (neuropathy), which reduces sensation. This means you might not notice small wounds or injuries until they become serious.
• Chronic Inflammation: Diabetes can lead to prolonged inflammation, which affects the wound healing process.

Signs of slow-healing wounds in diabetic patients

Some signs that your wounds are not healing as fast as they should are:

• Persistent pain
• Loss of sensation
• Swelling
• Fever and chills
• Bad odor from the wound
• Pus

Factors affecting diabetic wound healing

• High blood sugar levels

One major reason diabetic patients do not heal fast is high blood sugar levels. High sugar levels prevent the immune system from functioning properly and inflame the cells, thereby slowing down the healing process. High sugar levels also increase the thickness of the blood, making it even harder for blood to circulate properly. Diabetic patients soon develop peripheral vascular disease, which manifests in the blood vessels becoming narrow, further reducing blood flow to the limbs and slowing the diabetic wound healing process.
