Symptoms of Water in the Lungs
Water accumulation in the lungs, also known as pulmonary edema, is a serious medical condition. It's essential to recognise the symptoms early and seek proper medical treatment. This article will cover the primary symptoms of water in lungs like fatigue, shortness of breath, rapid breathing, chest pain and more.
What is Pulmonary Edema?
Pulmonary edema occurs when fluid collects in the air sacs of the lungs, making it difficult to breathe. This condition can result from various health issues such as heart problems, infections or exposure to certain toxins. Understanding the symptoms can help you identify the condition early and get the necessary treatment.

Pulmonary edema and pneumonia are two different lung conditions that may cause similar symptoms but have distinct causes and treatments. Pulmonary edema occurs when fluid builds up in the lungs air sacs, making it hard to breathe. This condition is most often linked to heart problems, especially congestive heart failure, where the heart can't pump blood effectively. As pressure builds in the lung’s blood vessels, fluid leaks into the alveoli, causing shortness of breath, a feeling of suffocation (especially when lying down), and in some cases, a frothy cough.
On the other hand, pneumonia is an infection of the lungs caused by bacteria, viruses, or fungi. It leads to inflammation and the filling of alveoli with pus or fluid. Symptoms include fever, productive cough, chest pain, chills, and fatigue. Pneumonia is often contagious, while pulmonary edema is not.
What are the Symptoms of Water in Lungs?
Fatigue Due to Lung Fluid Buildup
One of the initial symptoms of pulmonary edema is fatigue. When fluid builds up in the lungs, your body has to work harder to breathe. This extra effort can make you feel unusually tired, even after minimal physical activity. If you notice persistent fatigue without an apparent cause, it might be worth consulting a healthcare provider.
Shortness of Breath and Water in Lungs
Shortness of breath is a hallmark symptom of pulmonary edema. You may find it difficult to catch your breath, especially during physical activity or when lying down. This happens because the fluid in your lungs prevents oxygen from reaching your bloodstream efficiently.
Rapid Breathing with Fluid in Lungs
Another symptom to watch for is rapid breathing. When your lungs are filled with fluid, they must work harder to maintain oxygen levels in your body. This can cause you to breathe faster than usual, even when you're at rest. If you experience rapid breathing without a clear reason, it's essential to seek medical attention.
Chest Pain Related to Lung Fluid
Chest pain is another symptom that can be associated with pulmonary edema. The pain may feel like a pressure or tightness in your chest, and it can worsen when you lie down or exert yourself. This symptom should not be ignored, as it could indicate a more severe underlying issue, such as heart disease.
Wheezing and Water in Lungs
Wheezing, a high-pitched whistling sound when you breathe, can also be a sign of fluid in the lungs. Wheezing occurs because the airways become narrowed due to the fluid buildup, making it difficult for air to pass through.
Coughing Up Pink Frothy Sputum
Coughing up pink, frothy sputum is a particularly alarming symptom of pulmonary edema. The pink color comes from blood mixing with the fluid in your lungs. If you experience this symptom, seek emergency medical care immediately.
Other Pulmonary Edema Symptoms
- Sudden Weight Gain: Rapid weight gain can occur due to fluid retention in your body, including your lungs.
- Swelling in Lower Extremities: Swelling in your legs, ankles or feet can also indicate fluid buildup.
- Restlessness or Anxiety: Difficulty breathing can make you feel anxious or restless, especially at night.
What Causes Water in the Lungs?
Water in the lungs, medically known as pulmonary edema, occurs when fluid accumulates in the air sacs (alveoli) of the lungs, making it difficult to breathe. This condition can be life-threatening and is often linked to other health problems.
Common causes include:
- Heart-related conditions (Cardiogenic Pulmonary Edema): When the heart fails to pump efficiently such as in congestive heart failure, pressure builds up in the lungs’ blood vessels, pushing fluid into the alveoli.
- Acute respiratory conditions (Non-cardiogenic Pulmonary Edema): Caused by direct lung injury or inflammation, as seen in:
- Pneumonia
- Severe infections (sepsis)
- Inhalation of toxins or smoke
- Acute Respiratory Distress Syndrome (ARDS)
- Pneumonia
- Kidney disease: Poor kidney function can lead to fluid overload in the body, which may end up in the lungs.
- High-altitude pulmonary edema - HAPE: Some people experience fluid buildup in the lungs when exposed to very high elevations.
- Drug overdose or adverse medication reactions: Certain narcotics, chemotherapy drugs or reactions to blood transfusions can cause pulmonary edema.
How is Pulmonary Edema Diagnosed?
Diagnosing pulmonary edema involves evaluating symptoms, medical history and conducting specific tests to determine the cause and severity.
- Physical Examination: Doctors listen to your lungs for any unusual sounds and look for signs like quick breathing or swelling in your legs.
- Chest X-ray: This imaging test helps doctors determine if there's extra fluid in your lungs and assess whether the problem is related to your heart or another condition.
- Blood Tests: These tests check your oxygen levels, how well your heart is working and the condition of your kidneys.
- ECG (Electrocardiogram): This test examines your heart's rhythm and can help identify any issues related to your heart's function.
- Echocardiogram (Heart Ultrasound): This test assesses the heart's pumping function and evaluates the heart valves for abnormalities or signs of heart failure.
- Pulse Oximetry or ABG (Arterial Blood Gas): Doctors may use a simple device to measure how much oxygen is in your blood or perform a test that looks at your blood gases to see how well your breathing is working.
Treatment for Water in the Lungs
Treatment depends on the cause but focuses on removing excess fluid, improving oxygenation and treating the root condition. Here is how to remove fluid from lungs:
General treatment approaches:
1. Oxygen Therapy: This treatment uses a mask or small tubes in the nose to help people breathe better and increase the amount of oxygen in their blood.
2. Diuretics (Water Pills): These are medicines like furosemide, that help the body get rid of extra fluid through urination. They are especially useful for people with heart or kidney problems.
3. Blood Pressure Medicines: If someone has high blood pressure or heart failure, doctors might prescribe medications like ACE inhibitors, beta-blockers or vasodilators to help manage these conditions.
4. Treatment of the Cause:
- Infection: Antibiotics are used to treat infections like pneumonia or sepsis.
- Heart issues: Doctors may recommend medications, a pacemaker or surgery if necessary.
- Altitude-related: If someone is unwell because of high altitude, getting to a lower altitude quickly and providing oxygen support can help.
5. Mechanical Ventilation (In severe cases): Ventilators or non-invasive positive pressure devices like CPAP may be used if breathing becomes severely impaired.
Prevention Tips for water in lungs
Preventing pulmonary edema involves managing underlying conditions and making healthy lifestyle choices.
Manage Heart Health
- Regular Check-Ups: Regular visits to your doctor can help monitor and manage heart conditions.
- Medications: Take prescribed medications as directed to manage heart issues.
Healthy Lifestyle Choices
- Balanced Diet: Eat a balanced diet low in salt and rich in fruits, vegetables, and whole grains.
- Exercise: Engage in regular physical activity to maintain heart and lung health.
- Quit Smoking: If you smoke, seek help to quit.
When to Seek Emergency Medical Help?
Pulmonary edema is a medical emergency. You should consult a doctor immediately if you or someone else experiences:
- Sudden shortness of breath or gasping for air
- Chest pain or tightness
- Bluish lips, skin or fingertips
- Cough with frothy or pink-tinged sputum
- Rapid heartbeat or irregular pulse
- Severe anxiety, confusion or fainting
