This type of shock is characterized by breathing problems, hives, itching, a swollen throat and a sudden, dramatic fall in blood pressure.

Allergic reaction (anaphylaxis): Anaphylactic shock is a sometimes-fatal allergic reaction that can occur in people who are highly sensitive to drugs such as penicillin, to certain foods such as peanuts or to bee or wasp stings.

The bacteria then produce toxins that affect blood vessels, leading to a profound and life-threatening decline in blood pressure.

Severe infection (septic shock): Septic shock can occur when bacteria leave the original site of an infection (most often in the lungs, abdomen or urinary tract) and enter the bloodstream.

Endocrine problems: Such problems include complications with hormone-producing glands in the bodyвЂ™s endocrine systems specifically, an underactive thyroid (hypothyroidism), parathyroid disease, adrenal insufficiency (AddisonвЂ™s disease), low blood sugar and, in some cases, diabetes.

Certain medications: A number of drugs can cause low blood pressure, including diuretics and other drugs that treat hypertension heart medicationsВ such as beta blockers drugs for ParkinsonвЂ™s disease tricyclic antidepressants erectile dysfunction drugs, particularly in combination with nitroglycerine narcotics and alcohol.

A significant loss of blood from major trauma, dehydration or severe internal bleeding reduces blood volume, leading to a severe drop in blood pressure.

Decreases in blood volume: A decrease in blood volume can also cause blood pressure to drop.

Pregnancy: During the first 24 weeks of pregnancy, itвЂ™s common for blood pressure to drop.

Even mild dehydration (a loss of as little as 1 percent to 2 percent of body weight) can cause weakness, dizziness and fatigue. Fever, vomiting, severe diarrhea, overuse of diuretics and strenuous exercise can all lead to dehydration, a potentially serious condition in which your body loses more water than you take in.

However, dehydration does not always cause low blood pressure. Dehydration can sometimes cause blood pressure to drop.Most doctors will only consider chronically low blood pressure as dangerous if it causes noticeable signs and symptoms, such as: There is also no specific number at which day-to-day blood pressure is considered too low, as long as none of the symptoms of trouble are present. Within certain limits, the lower your blood pressure reading is, the better. National Hypertension Control Initiative.
