Sometimes we have blue or purple bruises on our bodies without even realizing it. We don't even remember if we hit the corner of a table or bumped into a door. But they are beautifully bruised. Sometimes, even a small bump can cause a big bruise. So what are these bruises, or what we call `(Ecchymosis)` in medical terms? Why do they form? Today, we will talk very simply and in a way that you can understand whether these are normal or something to be afraid of.
Simply put, what is this bruise?
A bruise is when the tiny blood vessels under our skin are damaged, causing some blood to leak out and collect under the skin. Think of it like a water pipe bursting and leaking out. But because there is no wound on our skin, that is, there is no cut on the surface of the skin, this blood does not come out. Instead, that blood collects under the skin, which is what we see as blue, purple, or black.
The medical term for this is Ecchymosis (pronounced "e-ka-mo-sis"). It's a bit of a complicated word, but it basically means the same "bruise" we all know. The blood cells in our bodies come together, repair the damaged blood vessels, and the bruise heals in a few days.
Are there any other bleedings that look like bruises?
Yes, there are several other ways that blood can pool under the skin and change color. These are slightly different from each other. Let's see what they are. Look at this table, and you will easily understand the difference.
| Type of bleeding | Simple description |
|---|---|
| Bruising (Ecchymosis) | This is the bruise we usually see. The skin surface is flat. It can be of different colors. |
| Hematoma | This is a larger collection of blood than a bruise. It can be caused by a car accident, a big fall, etc. It's like a lump protruding from the skin, and it hurts when you touch it. This is also the case when you get hit in the head. |
| Petechiae | These are very small, less than 2 millimeters to be exact, and look like small red dots. They do not turn white when pressed on the skin with a finger. These can be seen in diseases like dengue. |
| Purple (Purpura) | These are larger than those little dots (petechiae), but smaller than a regular bruise. These are also bleeding under the skin. |
Why do some people get hurt more easily than others?
Bruises are very common. Everyone gets a bruise at some point in their life. But some people get a big bruise even after a small bump, or they just get a bunch of bruises. There are several reasons why this can happen.
- Aging: As we age, our skin becomes thinner, and the protective layer of fat beneath the skin decreases. This makes blood vessels more susceptible to damage.
- Family history: Sometimes this is a genetic thing. If your mother or father were easily bruised, you may have the same tendency.
- Some medical conditions: Conditions like cancer and liver disease can cause bruising easily.
- Blood clotting disorders: People with diseases that make it difficult to stop bleeding, such as hemophilia and von Willebrand disease, often bruise.
- Low platelet count: Platelets are a type of cell that helps blood clot. When they are low, they bruise easily in a condition called thrombocytopenia.
- Vitamin Deficiencies: Vitamin C and vitamin K are two vitamins that are essential for blood vessel strength and blood clotting. A deficiency in these can lead to bruising.
- Medications: This is a very important point. Some medications can cause bruising easily.
- Blood thinners (e.g., aspirin, warfarin)
- Painkillers, especially the type called ``NSAIDs'' (e.g., ibuprofen, naproxen)
- Steroids
The most important thing is, if you're getting frequent, large bruises for no apparent reason, don't ignore it. Definitely see your doctor and talk about it.
Why does the color of a tarmac road change over time?
You may have noticed that a bruise is not the same color as it was at first, but after two or three days. It changes color and heals.
1. Initially (within a few hours): The bruise will appear red or pink because the blood that has come out of the vein contains oxygen.
2. After a day or two: As the blood loses oxygen, it turns blue or dark purple . Sometimes it can even appear black.
3. Between 5-10 days: The body now begins to break down and remove this accumulated blood. When the hemoglobin in the blood breaks down, it turns into greenish-colored substances called biliverdin and yellow-colored substances called bilirubin. This is why the bruise turns green, then yellow .
4. After 10-14 days: After the body has finally absorbed all of this, the bruise will turn brown and gradually fade.
So that color change means your body is healing the wound. That's a good sign!
What are the home remedies for a bruise?
Most bruises don't require major treatment. They heal on their own within a week or two. But there are some simple things you can do to help them heal faster and reduce pain.
- Rest and Elevation: Rest the injured area (e.g., arm, leg) as much as possible. When sitting or lying down, elevate the injured area slightly above your heart with a pillow. This will help reduce swelling.
- Ice application (first 1-2 days): It is best to apply ice immediately after the injury, or within the first 24-48 hours . This will constrict the blood vessels and reduce further bleeding.
- How to do it? Don't put ice cubes directly on your skin. Wrap them in a clean cloth or towel and hold them on the bruise for about 15 minutes . Do this several times a day.
- Warm compresses (after 2 days): After about two days, apply something warm. You can use a hot water bottle or a heated cloth. This will increase blood flow to the area and help the accumulated blood drain faster.
- Painkillers: If you are in pain, you can take a medicine like paracetamol (Acetaminophen). However, you should definitely ask your doctor before taking painkillers like NSAIDs (e.g., Ibuprofen), as these medications can sometimes increase bleeding.
When should you see a doctor?
A simple bruise is nothing to be afraid of. However, sometimes a bruise can be a sign of a serious problem inside the body. Therefore, if you have any of the symptoms below, be sure to seek medical advice.

| A lump with a bruise (Hematoma) | If the bruised area feels like a tight knot. |
| Other bleeding | If you have frequent nosebleeds, bleeding gums, or blood in your urine or stool. |
| Bruising around the eye | If there is an eye injury, a bruise around the eye, a change in vision, and severe pain. |

Take-Home Message
- An ecchymosis is when the blood vessels under the skin are damaged and some blood collects under the skin.
- Most of the time, these are not harmful and will heal on their own within about two weeks.
- Applying ice for the first two days after a bruise, followed by applying something warm, will speed up the healing process.
- If you have frequent, heavy bruising for no apparent reason, or any other unusual bleeding, don't ignore it. It could be a sign of a serious condition, so be sure to see your doctor.
- Some medications you take can also cause you to bruise easily. So tell your doctor about all the medications you take.
