Diabetes is a chronic condition that affects millions of people worldwide. It is characterized by high levels of blood sugar, which can lead to various complications if not managed properly.

Early detection and intervention are crucial in preventing these complications from developing further. While there are several diagnostic tests available to diagnose diabetes, some warning signs can be observed even through a simple handshake.

1. Tingling or Numbness

One of the early signs of diabetes is the sensation of tingling or numbness in the hands and fingers. This can be felt during a handshake, as the person with diabetes may have impaired nerve function due to high blood sugar levels.

If you experience this sensation or notice it in someone you are shaking hands with, it may be a cause for concern and should prompt further investigation.

2. Excessive Sweating

People with diabetes often experience excessive sweating, especially in their hands and feet. This can be attributed to the body’s attempt to flush out the excess sugar through sweat.

When shaking hands with someone who has diabetes, you may notice their palms being unusually moist or clammy, indicating this excessive sweating.

3. Slow Healing Wounds

Diabetes can affect the body’s ability to heal wounds. This can be observed through the texture or appearance of the hands while shaking hands. If you notice any slow healing wounds, cuts, or bruises, it may be an indication of diabetes.

Poor circulation and high blood sugar levels can impair the healing process, leading to delayed wound healing.

4. Weak Grip

Another warning sign that can be revealed during a handshake is a weak grip. Diabetes can cause muscle weakness and loss of strength, making it difficult to maintain a firm handshake.

If you notice someone struggling to exert pressure while shaking hands or their grip feels significantly weaker than expected, it can be a red flag for underlying diabetes.

5. Red, Swollen, or Itchy Hands

Changes in the appearance of the hands can also provide valuable information about a person’s health. Diabetes can lead to various skin conditions, such as redness, swelling, or itching.

When shaking hands with someone, if you notice any of these symptoms, it could be an indication of diabetes. The high blood sugar levels in diabetes can affect the skin’s integrity and lead to these visible signs.

6. Sweet or Fruity Odor

A distinctive fruity odor can sometimes accompany diabetes. This odor is caused by the body’s breakdown of fat instead of glucose for energy.

The byproducts of this process, known as ketones, can create a sweet or fruity smell that can be detected during a handshake. If you notice this peculiar odor, it may be wise to recommend further medical investigation for diabetes.

7. Rapid Weight Loss

Unintentional weight loss can be a warning sign of diabetes. When shaking hands with someone, if you notice that they have lost a significant amount of weight without trying, it may be indicative of an underlying health condition, such as diabetes.

High blood sugar levels can cause the body to break down stored fat and muscle for energy, leading to rapid weight loss.

8. Dry and Cracked Skin

Diabetes can cause dry skin, especially on the hands and feet. When shaking hands with someone, pay attention to the texture of their skin. If the skin feels excessively dry or appears cracked or flaky, it may be a sign of diabetes.

Elevated blood sugar levels can dehydrate the body and affect the skin’s moisture balance.

9. Increased Thirst and Urination

Excessive thirst, also known as polydipsia, and frequent urination, known as polyuria, are common symptoms of diabetes. When shaking hands with someone, observe if they seem excessively thirsty or frequently excuse themselves to use the restroom.

These signs can point towards the need for further evaluation for diabetes.

10. General Fatigue and Weakness

Diabetes can lead to general fatigue and weakness due to inadequate glucose utilization by the body’s cells. This can manifest as a lack of energy and feeling tired.

When shaking hands with someone, if they express persistent fatigue or appear physically weak, it may be an indication of diabetes.

Remember, while these warning signs can be revealed by a handshake, they are not definitive diagnostic criteria. It is essential to consult a healthcare professional for a proper diagnosis if you notice these signs in yourself or others.

Early detection and intervention play a vital role in managing diabetes and preventing complications.
