Unexplained Bruising on Your Body: Causes and Treatments

Too much sun

Although being in the sun is necessary to help the body produce vitamin D, too much sun exposure can damage your skin and cause you to bruise easily. Sunburn can take a long time to heal and its effects can be long-lasting.

The website Drugs.com warns that long-term overexposure to the sun’s harmful UV rays can cause the skin to bruise easily on exposed areas. This can even cause permanent discoloration to your skin. If you notice abnormal bleeding under your skin after a sunburn, you should call your doctor for a checkup.

If your skin shows signs of a sunburn, like reddened skin, skin tender to touch, and blisters, you can get relief from sunburn using natural remedies like aloe vera, honey, witch hazel, or oatmeal.

Intensive exercising

Intensive exercising can cause unexplained bruises in the parts of your body under stress. According to Dr. Debra Jaliman on WebMD, vigorous exercise like lifting weights or intensive training can cause tiny tears in blood vessels under the skin.

Also runner’s or jogger’s toenail is one of the most common reasons for bruised toenails as the toe pushes against the front of the shoe while running or jogging.

If you notice that you have bruising after working out that is unexplained or the result of an injury, you should follow the “RICE” method to help the bruise heal quicker. The RICE method for getting rid of a bruise is:

• Rest the injured limb.
• Ice the affected area. Remember that you should not put the ice directly on your skin.
• Compression to prevent swelling and inflammation.
• Elevation to prevent too much blood getting to the affected area.

Diabetes

If you suffer from diabetes, you may notice that you bruise easily and bruises last longer. Random bruising caused by diabetes occurs when the condition affects the blood vessels and causes peripheral vascular disease. Along with frequent unexplained bruising on your legs, diabetes causes increased thirst and urination, weight loss, nausea, and abdominal pain.

According to Dr. Melinda Ratini on WebMD, peripheral vascular disease commonly affects the legs.¹² The journal Physical Therapy says that a complication of diabetes is bruising or injuries that don’t heal.

Unexplained bruising on your legs is one of the signs of advanced diabetes. However, there are early warning signs of diabetes that can indicate you are at risk for developing the disease. If you have diabetes, it’s important to manage it properly. Your doctor may recommend controlling diabetes with diet or prescribe you medication.
