Low blood pressure causes may be due to heart problems, endocrine disorders, severe infection, allergic reaction, nutritional deficiency, and neurological disorder.
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.
6 Low Blood Pressure Causes
Low blood pressure causes are conditions that reduce the blood volume, reduce cardiac output and other health conditions.
Conditions that reduces blood volumes are dehydration (from diarrhea & vomiting), acute blood loss (bleeding peptic ulcer, after trauma, gunshot or knife wound), and organs inflammation.
Conditions that reduces cardiac output – are heart diseases such as weak heart muscle, Pericarditis (pericardium inflammation), pulmonary embolism, slow heart rate (bradycardia), and abnormally fast heart rate (tachycardia).
Other health conditions – that causes low blood pressure are vasovagal reaction, micturition syncope, adrenal insufficiency, septicemia, anaphylaxis (severe allergic reaction), and injury to the spinal cord.
Low blood pressure causes can be due to hormonal changes, widening of blood vessels, medicine side effects, anemia, heart, & endocrine problems.
- Heart problems: Some heart conditions can lead to low blood pressure such as extremely low heart rate (bradycardia), heart valve problems, heart attack, and heart failure. These conditions may prevent the body from being able to circulate enough blood.
- Endocrine system disorders: An under-active thyroid (hypothyroidism) or overactive thyroid (hyperthyroidism) can cause low blood pressure. Also, other conditions, such as adrenal insufficiency (Addison's disease), low blood sugar (hypoglycemia), and in some cases, diabetes can trigger low blood pressure.
- 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.
- 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.
- Nutritional deficiency: A lack of the vitamins B-12 and folate 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.
- Neurological disorder: multiple system atrophy (nervous system damage) and Shy-Drager syndrome (progressive damage to the autonomic nervous system).
