Athletes and people who are exercises regularly tend to have lower pressure than do people who are not as fit.

However, in some instances, low blood pressure can be a sign of serious, even life-threatening disorders.

Low BP Causes

Causes of low blood pressure may be due to pregnancy, medications, heart problems, endocrine problems, dehydration, blood loss, severe infection, allergic reaction, and nutritional deficiencies.

Low blood pressure caused by pregnancy: Because a woman's circulatory system expands rapidly during pregnancy, blood pressure is likely to drop. In fact, during the first 24 weeks of pregnancy, systolic pressure commonly drops by five to 10 points and diastolic pressure by as much as 10 to 15 points.

Low BP caused by medications:  Many medication drugs can cause low blood pressure, including Diuretics (and other drugs that treat high blood pressure), Heart medications (such as beta blockers), Drugs for Parkinson's disease,  Tricyclic antidepressant’s sildenafil (Viagra), and Some over-the-counter medications can cause low blood pressure when taken in combination with medications used to treat high blood pressure.

Causes of Low blood pressure by heart problems: Some heart conditions that can lead to low blood pressure include extremely low heart rate (bradycardia), heart valve problems, heart attack, and heart failure. These conditions may cause low blood pressure because they prevent the body from being able to circulate enough blood.

Low BP caused by endocrine problems: An under-active thyroid (hypothyroidism) or overactive thyroid (hyperthyroidism) can cause low blood pressure. In addition, other conditions, such as adrenal insufficiency (Addison's disease), low blood sugar (hypoglycemia), and in some cases, diabetes, can trigger low blood pressure.

Low blood pressure caused by dehydration: When one becomes dehydrated, the body loses more water than it takes in. Even mild dehydration can cause weakness, dizziness, and fatigue. Fever, vomiting, severe diarrhea, overuse of diuretics, and strenuous exercise can all lead to dehydration. Far more serious is hypovolemic shock, a life-threatening complication of dehydration. It occurs when low blood volume causes a sudden drop in blood pressure and a corresponding reduction for oxygen reaching your tissues. If left untreated can lead to severe hypovolemic shock, that can cause death within a few minutes or hours.

Low BP caused by blood loss: Losing a lot of blood from major injury or severe internal bleeding reduces the amount of blood in the body, leading to a severe drop in blood pressure.

Low blood pressure caused by severe infection: Septicemia can happen when an infection in the body enters the bloodstream. Lung, abdomen, or urinary tract infections are usually the cause of septicemia. These conditions can lead to a life-threatening drop in blood pressure called septic shock.

Hypotension caused by allergic reaction: Anaphylaxis is a severe and potentially life-threatening allergic reaction. Common triggers of anaphylaxis include foods, certain medications, insect venoms, and latex. Anaphylaxis can cause breathing problems, hives, itching, a swollen throat, and a drop in blood pressure.

Hypotension caused by nutritional deficiency: A lack of the vitamins B-12 and foliate can cause anemia, a condition in which your body does not produce enough red blood cells. In addition to making, you feel tired because you are not getting enough oxygen; anemia can lead to low blood pressure.
