What is a Dangerous Low Blood Pressure for a Woman?

Low Blood Pressure in Women: Causes & Warning Signs

When the force of blood exerted on the artery walls while flowing through them is too low, the condition is diagnosed as low blood pressure or hypotension. According to the National Heart, Lung, and Blood Institute, blood pressure readings lower than 90/60 are defined as low blood pressure.

Women's blood pressure readings can fluctuate throughout the day for various reasons. This doesn’t cause any significant complications, but extremely low blood pressure can lead to serious health issues. Thus, it is essential to understand the implications of low blood pressure for women.

What are the Causes of Low Blood Pressure in Women?

Blood pressure levels change throughout the day due to various factors. Certain individuals are genetically predisposed to having low blood pressure. Here’s a breakdown of the causes of low blood pressure in women:

• Dehydration : If the body lacks fluids or is dehydrated for a long time, then blood volume decreases, causing a drop in blood pressure.   
• Loss of Blood : If blood loss is due to a major injury or surgery, then blood pressure can drop significantly.
• Cardiac Issues : Cardiac disorders like bradycardia (slow heart rate) or heart valve problems can reduce the efficiency of heart function. This substantially affects blood pressure levels as the heart cannot efficiently circulate blood throughout the body.
• Endocrine Disorders : Ailments like diabetes or low blood sugar can lead to hypotension. Disorders like adrenal insufficiency and hypothyroidism can cause an imbalance in hormones, leading to low blood pressure.
• Side Effects of Medicines : If you are taking medications for high blood pressure, depression, or heart disease, then it can lead to low blood pressure or hypotension as a side effect.
• Pregnancy : Women experience hormonal changes during pregnancy, which cause blood vessels to relax, causing a drop in blood pressure level, specifically during their first and second trimesters.
• Infections : Allergic reactions like septic or anaphylactic shock are serious, life-threatening conditions that can lead to dangerously low blood pressure levels.
• Nutritional Deficiency : Lack of essential nutrients such as vitamin B12 and folic acid can cause hypotension or low blood pressure.
• Neurally Mediated Hypotension : This disorder causes an extreme drop in blood pressure levels after standing for prolonged hours. It usually affects young women and children. The cause is a lack of communication between the heart and the brain.

What are the Symptoms of Low Blood Pressure in Women?

Low blood pressure does not result in any severe health issues. However, if this condition continues, you may encounter the following symptoms:

1. Dizziness : This is a result of orthostatic hypertension or postural hypotension. People with this disorder experience dizziness due to a sudden decline in blood pressure levels when they stand up after sitting for long hours. It can happen due to dehydration, pregnancy, long-term bed rest, or side effects of certain medicines. It is common in older adults.   
2. Fatigue : Feeling tired and weak for a long time can indicate consistent low blood pressure.  
3. Fainting : Low blood pressure decreases blood flow to the brain, and the person can sometimes become unconscious.
4. Blurred Vision  : Due to dizziness and fatigue, you may experience blurred vision or difficulty focusing.
5. Cold and Clammy Skin : Sticky and cold skin, accompanied by a prolonged feeling of sickness, can be signs of low blood pressure.  
6. Nausea : You can feel digestive discomfort or vomiting due to reduced blood circulation.  
7. Shock : Severely low blood pressure levels can cause confusion, shallow breathing, or rapid pulse.

Due to hormonal changes during pregnancy, women are more susceptible to low blood pressure. However, if this condition persists or the symptoms worsen, seek immediate medical attention. If you are experiencing a sudden drop in blood pressure or losing consciousness frequently, urgent medical care is required.
