Conditions that reduce the volume of blood, reduce cardiac output (the amount of blood pumped by the heart), and medications are frequent reasons for low blood pressure. Here are some conditions where you can get low blood pressure.
Because a woman’s circulatory system expands rapidly during pregnancy, blood pressure is likely to drop. During the first 24 weeks of pregnancy, systolic pressure commonly drops by five to 10 mm Hg and diastolic pressure by as much as 10 to 15 mm Hg. This is normal, and blood pressure usually returns to your pre-pregnancy level after you’ve given birth.
2. 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 your body from being able to circulate enough blood.
3. Endocrine problems
An underactive 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.
When you become dehydrated, your 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.
5. Lack of nutrients in your diet
A lack of the vitamins B-12 and folate can cause anemia, a condition in which your body doesn’t produce enough red blood cells, causing low blood pressure.
There are several kind of drugs which may lead low blood pressure to you, include: Alcohol, Anti-anxiety medications, Certain antidepressants, Diuretics, Heart medicines including those used to treat high blood pressure and coronary heart disease, Medications used for surgery, and Painkillers.
