One of the most important causes of swollen feet is diastolic heart muscle failure and its definition is the inability of the heart muscle to expand and expand and fill it with sufficient blood needed to meet the requirements of vital and important body organs such as the heart, brain, kidneys, liver and extremities, and this may lead to an increase in the rate of pulmonary artery pressure and also high pressure in The chambers of the right heart, such as the right ventricle and the right ventricle, and then to the central vein hypertension, and this leads to the backflow of fluids in the body, including the feet, ankles, and legs, for example, high blood pressure, coronary artery disease, chronic rheumatic heart valve diseases, and pericardial diseases surrounding the heart.

And also one of the important reasons is the failure of the right heart muscle with its enlargement, expansion and failure, which is accompanied by regurgitation of the tricuspid valve located between the right atrium and the right ventricle, and this occurs in cases of chronic lung diseases, such as lung fibrosis and chronic bronchoconstriction .. in addition to chest sensitivity or chronic asthma and also in Cases of chronic pulmonary artery diseases such as pulmonary artery hypertension, the presence of thrombosis and thrombosis in the pulmonary arteries, or due to the presence of congenital narrowing of the pulmonary arteries, and one of the important causes is also chronic kidney disease and the loss of protein in the urine, or what is known medically as albuminuria.

And also one of the reasons is chronic liver disease, for example cirrhosis and viral hepatitis where the liver''s ability to produce proteins is lacking, and among the reasons is also lack of absorption and loss of proteins in the lumen of the gastrointestinal tract, for example chronic infections in the wall of the small intestine, for example Crohn''s disease and also infections Chronic colon wall.

For example, Serratif Colitis disease, and one of the reasons is also the side effects of some drugs that are used to treat pressure widening of the arteries, such as amor, hydralazine, and methyldopa, as well as the chronic use of cortisone, and also the use of some analgesics such as: Furtarin, Bruin and others that cause fluid backflow in the body, and also one of the reasons is laziness in Thyroid function.

One of the reasons is also the lack of movement and sitting on a chair for a long time .. as in cases of paraplegia, strokes and brain hemorrhage, as blood flow to the heart decreases, which causes fluid to regurgitate in the feet.

One of the reasons is obesity, and pregnancy is also one of the reasons that lead to swollen feet, especially in the last months of pregnancy.

Also, elephantiasis in 30% of cases causes swollen feet together, which is due to blockage in the lymph ducts, and finally in a proportion of people there is no clear cause of swollen feet.
