    Top Symptoms:

    Urgency:
    Primary care doctor
  2. 2.Low Blood Cell Counts Due to a Chronic Disease

    Anemia is a condition in which the body does not have enough healthy red blood cells, which are cells that provide oxygen to body tissues. Anemia of chronic disease is anemia that is found in people who already have certain long-term (chronic) medical conditions.

    Long-term condition with a variable course, highly dependent on the underlying cause.

    Rarity:
    Common
    Top Symptoms:
    fatigue, shortness of breath on exertion, decreased exercise tolerance, dizziness when standing up, pale skin all over

  5. 5.Chronic Obstructive Pulmonary Disease (Copd)

    COPD (chronic obstructive pulmonary disease) is a chronic condition of the lungs and the airways in the lungs. Damage has occured due to long-term exposure to substances that irritate and damage the lungs, such as cigarette smoke or air pollution. This damage can cause symptoms like shortness of breath, decreased exercise tolerance and cough. A common cold or other types of infection can cause symptoms to worden acutely, this is called an exacerbation.

    Often a lifelong condition

    Rarity:
    Common
    Top Symptoms:
    fatigue, cough and dyspnea related to smoking, cough, shortness of breath, trouble sleeping
    Symptoms that always occur with chronic obstructive pulmonary disease (copd):
    cough and dyspnea related to smoking
    Symptoms that never occur with chronic obstructive pulmonary disease (copd):
    rectal bleeding
    Urgency:
    Primary care doctor
  6. 6.Right Heart Failure (Cor Pulmonale)

    Cor pulmonale is known as right heart failure and is often a long-term consequence of high blood pressure or COPD.

    Treatment depends on severity of illness.

    Rarity:
    Common
    Top Symptoms:
    fatigue, chest pain, shortness of breath on exertion, wheezing, decreased exercise tolerance
    Symptoms that never occur with right heart failure (cor pulmonale):

    Urgency:
    Hospital emergency room
  8. 8.Peripheral Arterial Disease (Pad)

    Peripheral artery disease (PAD) occurs when the big blood vessels, called arteries, become too narrow due to clumps of fat (called plaques) building up inside the walls. If arteries become too narrow, not enough oxygen and nutrients are delivered to the muscles, skin, and organs. The arteries in the legs are often affected first, as they are the furthest from the heart.At first, PAD has no symptoms. As it gets worse, leg pain is likely to develop, leading to cramps in the calf, thigh, foot, or buttock upon exercise. PAD can also increase the risk of a blood clot if a piece of plaque detaches, leading to serious complications such as a heart attack or stroke.Peripheral artery disease is much more common in smokers and in people with diabetes. High blood pressure, high cholesterol, being overweight, and not getting much exercise also can put one at higher risk.

    The prognosis of this disease is highly variable and depends heavily on habits, medical history, and genetics. Peripheral artery disease is a chronic non-life threatening condition. Managing the disease, however, is very important in reducing the risk for stroke and heart attacks, so make sure to follow-up with a physician.

    Rarity:
    Common
    Top Symptoms:
    leg numbness, spontaneous foot pain, decreased exercise tolerance, cold feet, thigh pain
    Symptoms that never occur with peripheral arterial disease (pad):
    calf pain from an injury, thigh pain from an injury
    Urgency:
    Primary care doctor
  9. 9.Chest Pain From Reduced Cardiac Blood Flow (Angina Pectoris)

    Angina pectoris is chest pain that is felt when heart muscle needs more blood than it is currently getting. This may result from coronary artery disease (CAD). CAD happens when the arteries that supply blood to heart muscle become hardened and narrowed. This is due to the buildup of cholesterol and other material, called plaque, on their inner walls.

    Angina pectoris is reflective of underlying heart disease, which is a chronic condition once it develops.

    Rarity:
    Common
    Top Symptoms:
    chest pain, chest pain, tight, heavy, squeezing chest pain, moderate chest pain, deep chest pain, behind the breast bone
    Symptoms that always occur with chest pain from reduced cardiac blood flow (angina pectoris):
    chest pain
    Symptoms that never occur with chest pain from reduced cardiac blood flow (angina pectoris):
    productive cough
    Urgency:
    Primary care doctor
