Do you sometimes feel a little puffy and heavy when you wake up in the morning? Or do you feel like you've been sitting in an office chair all day, or sitting on the bus for a long time, and then getting off the bus, your legs and ankles are very swollen, and your shoes feel tight? This is really something that happens to many people. In medicine, we call this condition swelling or 'edema'. Most of the time, this is nothing to worry about, but sometimes it can be a symptom of another serious illness inside our body. So, it's very important to know everything about this without panicking. Let's talk about this simply today.
So, what exactly is edema?
Simply put, edema is the accumulation of fluids, especially water, in the tissues of our body, causing them to swell. Imagine that our bodies are filled with a network of tiny tubes called blood vessels and lymphatic vessels. These are the fluids that carry the body's needs and remove waste products. Sometimes, when something goes wrong with this system, some of this fluid leaks into the tissues and accumulates there. That's when that area swells.
This swelling can occur anywhere on the body, but is most commonly seen in:
- On two legs
- Ankles are fine.
- On the feet
- In both hands
- On the face
Although this can happen to anyone of any age, it is more common in pregnant women and people over the age of 65. Most of the time, if it is a minor swelling, it will go away on its own within a day or two. So it is difficult to say exactly how common this is.
What are the symptoms of bloating? How do you recognize it?
It's not that difficult to recognize that you have swelling. The main symptom is that a certain area of your body feels larger and more swollen than usual. You can also pay attention to these things.
| Symptom | How you feel/look |
|---|---|
| Puffy/enlarged appearance | A part of the body (e.g., leg, arm) appears larger and bloated than usual. |
| Skin change | The skin at the swollen area is very stretched and looks shiny. |
| Heaviness and stiffness | The swollen area feels tight and heavy, as if it's filled with something inside. |
| Difficulty walking | When your legs, ankles, or feet swell, it can be difficult to walk and feel numb. |
| A little pain | Sometimes you may feel a slight ache or pain at the swollen area. |
| Coughing or difficulty breathing | This is a more serious symptom. This can happen if fluid accumulates in the lungs (pulmonary edema). |
Why does my body swell like this? What are the causes?
There is not one cause of swelling, there can be many. When you go to see a doctor, the first thing he or she will do is find out what is causing your swelling.
| Reason | A simple explanation |
|---|---|
| Gravity | When you stand or sit in the same position for a long time, the fluid in your body naturally accumulates in your legs and feet due to gravity. This is also called ``dependent edema``. |
| Venous Insufficiency | The veins in our legs have small valves inside them. These stop the blood from flowing down and push it up, towards the heart. When these valves become weak, the blood does not flow up properly and pools in the legs. This is also related to the phenomenon of varicose veins. |
| Other underlying diseases | Swelling can also be a symptom of other diseases, such as heart failure, lung, liver, kidney, or thyroid disease . This is a very important point. |
| Side effects of medications | Some medications, for example, some medications for high blood pressure and painkillers, can also cause swelling as a side effect. |
| Improper nutrition | If you don't eat a well-balanced diet, especially if you add too much salt (sodium) to your food, your body can retain water and swell. The dried meat/fish, sausages, sauces, and packaged foods we eat are high in salt. |
| Pregnancy | During pregnancy, as the uterus grows, the large blood vessels in the lower abdomen become compressed. Therefore, it is common for the legs to swell, obstructing blood flow from the legs upward. |
| Immune system problems | Swelling can also be caused by an allergic reaction, infection, burn, injury, or blood clot. |
How does the doctor diagnose this? Are there levels of swelling?
When you go to see a doctor, he or she will first examine your body. He or she will pay attention to things like swelling, skin color, and shine.
Then there's a special test he does. It's called the 'pitting test.' What you do here is press your finger firmly on the swollen area for about 5 to 15 seconds. If a small pit forms when you remove your finger, it confirms that fluid has accumulated in the tissue.
The severity of swelling is divided into several levels depending on how quickly these lesions return to normal.
| Grade | Pit Depth | Rebound Time |
|---|---|---|
| Grade 1 | A small hole about 2 millimeters in size | It returns to normal as soon as it is pressed. |
| Grade 2 | A hole about 3-4 millimeters | Recovers in less than 15 seconds. |
| Grade 3 | A hole about 5-6 millimeters | It will recover in 15 to 60 seconds. |
| Grade 4 | A groove about 8 millimeters deep | It takes about 2-3 minutes to get back to normal. |
How do you treat swelling?
The treatment for swelling depends on the cause. Rather than simply giving medication to reduce swelling, doctors try to treat the underlying cause.
- If it is due to a lung disease: For example, if it is due to a disease like `(Emphysema)` or `(Chronic Bronchitis)`, if you are a smoker, your doctor will advise you to stop smoking completely.
- If you have a condition like chronic heart failure , you may be told to control your weight, limit your daily water intake, and control the amount of salt in your diet. If you drink alcohol, you may also be told to cut down on it.
- A side effect of a medication: If it turns out that the swelling is caused by a medication you're taking, your doctor may stop the medication, reduce the dose, or switch you to another medication.
Remember one very important thing: Never stop taking any medication or change the dosage on your own without consulting your doctor. Doing so may worsen your other medical conditions.
What can you do at home to reduce swelling?
While treating the cause, there are a few simple things you can do yourself to reduce the discomfort caused by swelling.
- Elevate your legs: When you're sitting or lying down in bed, place two or three pillows under your legs, keeping them above the level of your heart. This helps fluid flow back into your body against gravity.
- Don't stay in the same position: Don't sit or stand in the same place for too long. Get up and walk around a bit, moving your legs, at least once an hour.
- Use special socks: Support socks or compression stockings are available at pharmacies. These provide gentle pressure to the swollen area and help prevent fluid from accumulating.
- Reduce salt: This is very important. Reduce the amount of salt you eat. Reduce the amount of salt in canned foods, sauces, sausages, pickles, and dried fish as much as possible.
- Follow your doctor's advice: You may be given a diuretic (commonly called a 'water pill') that helps your body get rid of excess water in the urine. Take the medicine at the right time.
In what situations do you need to see a doctor urgently?
Even if it's just normal swelling, if there are certain symptoms, it could be an emergency. If that's the case, you should see a doctor right away.
| If you have these symptoms, seek medical advice immediately. |
|---|
| If there is severe pain, redness, or skin discoloration in the swollen area. |
| If the skin has broken and an open wound has formed in the swollen area. |
| If you have difficulty breathing or chest pain . This is an emergency, go to the nearest hospital Emergency Department (ETU) immediately. |
| If only one leg or arm suddenly swells (this could be a sign of a blood clot). |
| If the swelling is so severe that you cannot walk or move your body. |
Swelling is not something to just ignore. Sometimes it can be the first sign of a more serious condition. So if you have unusual swelling, it's always wise to see a doctor to find out the cause.
