Pulmonary hypertension is a serious lung condition. It happens when the blood pressure in the arteries of your lungs becomes too high. This makes it harder for your heart to pump blood through your lungs. As a result, you may feel tired or short of breath. In this blog, we will explain what pulmonary hypertension is, the main causes, and the signs of pulmonary hypertension. We will also cover common pulmonary hypertension symptoms and when to see a doctor.

What Is Pulmonary Hypertension?

Pulmonary hypertension means high blood pressure in the arteries of the lungs. These arteries carry blood from your heart to your lungs. Normally, blood flows easily through them. However, when the pressure rises, your heart must work harder. Over time, this can weaken your heart. It can also cause other health problems. Unlike regular high blood pressure, pulmonary hypertension affects only the lungs and the right side of the heart. Because of this, it is important to know the difference.

Causes of Pulmonary Hypertension

There are many causes of pulmonary hypertension. Sometimes, doctors cannot find a clear reason. But often, it is linked to other health problems. Here are some common causes:

Heart diseases: Problems with the left side of the heart can increase pressure in the lungs.

Lung diseases: Conditions like chronic obstructive pulmonary disease (COPD) or scarring of the lungs can lead to this problem.

Blood clots: Clots in the lung arteries can block blood flow and raise pressure.

Genetic factors: Some people inherit genes that make them more likely to get pulmonary hypertension.

Other conditions: For example, sleep apnea, liver disease, or autoimmune diseases can also cause it.

Unknown causes: Sometimes, the cause is not known. Doctors call this idiopathic pulmonary hypertension.

Symptoms of Pulmonary Hypertension

Symptoms of pulmonary hypertension can be mild at first. However, they often get worse over time. Here are some common signs of pulmonary hypertension:

Shortness of breath, especially during activity

Feeling tired or weak

Chest pain or pressure

Swelling in the ankles, legs, or belly

Fast heartbeat or palpitations

Feeling dizzy or fainting

Bluish lips or skin (in severe cases)

Because these symptoms can look like other problems, it is important to pay attention to changes in your health.

When to See a Doctor

If you notice any of the symptoms above, you should talk to a doctor. Especially if you feel short of breath or faint often, do not wait. Early treatment can help manage the condition. If you have a family history of pulmonary hypertension or related heart and lung diseases, let your doctor know. Sometimes, symptoms can be mild at first. But they may get worse quickly. Therefore, it is better to seek advice early.

Conclusion

Pulmonary hypertension is a serious condition that affects the lungs and heart. It can cause symptoms like shortness of breath, tiredness, and swelling.
