Here are some of the causes of fluid retention in our bodies

Sometimes in our bodies, fluid leaks from the blood into the body tissues. Our body is made up of a system of tubes known as the lymphatic system whose work is to drain this fluid from the body tissues back into the blood. When this does not occur, the fluid is retained in the tissues leading to a condition known as oedema or fluid retention. 

Fluid retention can either be generalized oedema where there is swelling throughout the body, or localized oedema where only specific parts of the body swell. Common symptoms include bloating, swelling and puffiness. Fluid retention can lead to serious medical conditions and one should consult a doctor and not self-treat. To be on the safe side, it is good to know what can trigger one. Here are 8 causes of fluid retention. 

1. The Heart

The pumping of the heart usually regulates blood pressure within the blood vessels. If the heart starts to fail, the blood pressure is affected. This consequently leads to water retention. In this case, the legs, feet and ankles usually swell. The fluid can also build up in the lungs leading to breathing complications. 

2. Pregnancy

During pregnancy, the uterus exerts weight on major veins that are found in the pelvis. This causes fluid to buildup in the body. It is not a serious problem and in most cases it eases after childbirth. 

3. Capillaries

Fluid that is rich in nutrients and oxygen, referred to as interstitial fluid, usually nourishes the body cells before being transported back into the capillaries.  If there is something wrong with the pressure in the capillaries, excess liquid is released into the spaces in between the cells. Too much fluid being released into the cells leads to swelling and water retention.

4. The Kidney 

The kidney plays a vital role in eliminating waste products from our body. When there is irregular blood flow to the kidney, its working is affected and waste products including fluids are not eliminated. This leads to fluid retention.  

5. Physical Inactivity 

Lack of physical activity reduces blood circulation and blood can begin to accumulate in the legs. This causes a high pressure in the capillaries leads to fluid leaving the capillaries at a high rate. The pressure also makes it difficult for the fluid to move back into the capillaries. This then leads to fluid retention. This can happen especially in long-haul flights. Making minor movements where possible can help reduce the fluid retention.
