left sided heart failure

Explanation:

The woman exposed in the question has many symptoms caused by heart failure on the left side.

Heart failure is a long-term chronic disease, although it can sometimes develop suddenly. It can affect only one side of the heart and is called, depending on the case, right heart failure or left heart failure. Even if it develops on only one side of the heart, both sides are affected as time goes on.

Because the heart's pumping function is impaired, blood may return to other areas of the body, accumulating, for example, in the lungs, liver, gastrointestinal tract, arms and legs. Hence the other name given to the disease: congestive heart failure. Thus, oxygen and nutrients are lacking in the organs where blood has accumulated, impairing and reducing their ability to work properly.

Left heart failure causes fluid to accumulate in the lungs and consequently shortness of breath. Initially, shortness of breath occurs only during exertion, but as heart failure progresses, shortness of breath begins to occur with less effort and finally even at rest. People with severe left heart failure may find themselves short of breath when lying down (a condition called orthopnea) as gravity causes more fluid to enter the lungs. These people often wake up panting or wheezing (a clinical condition called paroxysmal nocturnal dyspnea). When sitting, some of the fluid is drained to the lower lungs, which makes breathing easier. People with left heart failure feel tired and weak during physical activity because their muscles are not getting enough blood.

because health skills are tools and strategies and also practical skills are also something you need to learn (like tools and strategies) and put it in reality.
