Blood frequently leaks fluid into bodily tissues. This fluid, known as lymph, is excreted back into the bloodstream by the lymphatic system, a network of channels that runs throughout the body.

Among the numerous widespread reasons few are listed below:

Non-medical origin

• Against Gravity: Blood is kept in your lower extremities by gravity. Regularly standing up and moving about will help to keep the blood circulating. Plan time to get yourself up and move about if you’re employed in a desk job.
• In Flights: Your body may begin to hold onto water if the cabin pressure changes or you sit for a long time on a long journey.
• During Summer: The body is less effective at removing fluid from tissues during the summer because of the heat.

Fluid retention can affect following vital organs:

Brain

• Cerebral edema is the medical term for fluid retention in the brain. This may result in symptoms like nausea, headaches, blurred vision, and balance issues.
• This is an emergency like situation and requires immediate treatment.

Lungs

• Pulmonary edema, or an accumulation of fluid in the lungs, is a dangerous sign that something is wrong with the heart or respiratory system.
• Breathing issues, a cough with sputum, chest pain, and weakness are signs of the condition, which can impair the lungs capacity to deliver oxygen to rest of the body.

These early warning indications of peripheral edema are typical:

• An arm or leg begins to feel heavy or full.
• Your jewelry or clothing begins to feel constrictive and uncomfortable.
• Skin close to the edema feels constrictive or heated.
• Affected joints become more difficult to move.
• Swelling of the affected body parts, usually the hands, feet, and ankles afflicted body parts begin to hurt.
