Unexplained Bruising: Causes, Concerns, and When to See a Doctor

Frequent bruising?

I recently noticed severe unexplained bruising all over my legs after waking up.
It doesn't hurt when I press on it, and the bruises seem to be getting larger.
Can you provide an explanation? Should I see a doctor? Which specialty should I consult?

Dear Xiao T,
This is Dr.
Lin Ming-Hsing from the Family Medicine Department at Tainan Hospital, Department of Health.
First, let's rule out any deficiency in platelet count.
If necessary, it may be advisable to visit either the Hematology Department or the Family Medicine Department to check for platelet count or other related hematological or vascular diseases.
(I recommend a high intake of Vitamin C.)
Tainan Hospital, Department of Health, cares about you.

More Info

Unexplained bruising can be concerning, especially when it appears suddenly and without any apparent cause. In your case, waking up to find significant bruising on your legs that is not painful to the touch raises several questions about potential underlying issues.
Bruising occurs when small blood vessels, known as capillaries, break and leak blood into the surrounding tissue. This can happen due to various reasons, including trauma, certain medical conditions, or even medication side effects. Here are some potential causes for your symptoms:
1. Trauma or Injury: Sometimes, people may not remember bumping into something or may have a minor injury that they overlooked. Even small impacts can lead to bruising, especially if you have sensitive skin or are prone to bruising.

2. Blood Disorders: Conditions such as thrombocytopenia (low platelet count), hemophilia, or other clotting disorders can lead to easy bruising. These conditions affect the blood's ability to clot properly, resulting in bruises from minor injuries.

3. Medications: Certain medications, particularly blood thinners (like aspirin, warfarin, or certain anti-inflammatory drugs), can increase the likelihood of bruising. If you are taking any medications, it’s essential to review their side effects.

4. Nutritional Deficiencies: Deficiencies in vitamins, particularly Vitamin C and Vitamin K, can lead to increased bruising. These vitamins play crucial roles in blood vessel health and clotting.

5. Aging: As people age, their skin becomes thinner and loses some of the protective fatty layer beneath it, making bruising more common.

6. Medical Conditions: Conditions such as liver disease, certain cancers, or vasculitis can also cause unexplained bruising. These conditions can affect blood clotting or the integrity of blood vessels.

Given that your bruising is extensive and worsening, it is advisable to seek medical attention. You should see a healthcare provider who can evaluate your symptoms and medical history. The best course of action would be to visit a primary care physician or a hematologist (a specialist in blood disorders). They can perform a physical examination and may order blood tests to assess your platelet count, clotting factors, and overall blood health.

In the meantime, keep track of any additional symptoms you may experience, such as fatigue, weakness, or any other unusual signs. This information can help your doctor make a more accurate diagnosis.
In summary, while unexplained bruising can sometimes be benign, it is essential to take it seriously, especially if it is extensive and worsening. Seeking medical advice is the best way to ensure that any underlying issues are identified and addressed appropriately.
