Blood pressure changes naturally throughout the day. Low blood pressure can be the result of a temporary problem, such as dehydration, or a more long-term problem, such as heart disease. Low blood pressure can be genetic or a result of aging. In some cases, a temporary factor such as pregnancy or dehydration is responsible. In others, low blood pressure is due to an underlying disease or severe reaction. Changing dietary habits may be enough to treat temporary causes of low blood pressure. Alternatively, your doctor may prescribe medication or change your existing treatment plan if it is likely responsible for the symptom. Anyone with symptoms of low blood pressure, such as dizziness and fatigue, should get medical attention. What causes low blood pressure? The cause of low blood pressure is not always clear. It may be related to the following factors:

• Pregnancy
• Hormonal problems such as hypothyroidism (hypothyroidism), diabetes or low blood sugar (hypoglycemia)
• Some over-the-counter medications
• Some prescription drugs, such as those for high blood pressure, depression or Parkinson's disease
• Heart failure
• Cardiac arrhythmia (abnormal heart rhythm)
• Dilatation or dilation of blood vessels
• heat exhaustion or heat stroke
• Hepatic diseases

Primary causes of low blood pressure There are several causes of low blood pressure. Some of them are temporary and can be easily fixed. Low blood pressure can also be a sign of a health problem or emergency. Treatment may be necessary. Several health conditions can cause low blood pressure. These include:

• Addison's disease (low levels of adrenal hormones)
• anaphylaxis (severe allergic reaction)
• anemia
• Blood loss
• bradycardia (low heart rate)
• hydration
• Diabetes or low blood sugar
• heart attack or heart failure
• heart valve problem
• hypothyroidism (low levels of thyroid hormones)
• hepatic insufficiency
• parathyroid disease
• pregnancy Septic shock (the result of a serious infection)
• Orthostatic hypotension or postural low blood pressure
• trauma or head injury

Treatment To address low blood pressure, your doctor may adjust the dose of your existing medication or prescribe drugs to increase your blood pressure. Medications they may prescribe include fludrocortisone and midodrine. In addition, a person can benefit from:

• drinking more water throughout the day
• avoidance of alcohol, which can cause dehydration
• eat more healthy foods high in sodium
• drinking tomato juice or sports drinks
• Wearing compression socks that reach the thighs or waist
• moving the legs to stimulate blood flow before getting out of bed
