TLDR;
This video explains low diastolic blood pressure, defining it as a reading less than 60 mmHg, and discusses its causes, symptoms, and potential treatments. It highlights that while low blood pressure is not always an emergency, sudden drops accompanied by specific symptoms require immediate medical attention due to severe consequences like stroke or heart attack. The video also covers lifestyle adjustments and medical interventions to manage low diastolic blood pressure.
- Diastolic blood pressure is the lower number in a blood pressure reading, indicating artery pressure when the heart rests.
- Low diastolic blood pressure is generally considered below 60 mmHg.
- Sudden drops in blood pressure with symptoms like dizziness or blurred vision require immediate medical attention.
Understanding Diastolic Blood Pressure [0:25]
Diastolic blood pressure is the lower number in a blood pressure reading, representing the pressure in your arteries when the heart is resting between beats. For example, if your blood pressure is 120/80, the diastolic pressure is 80. While official guidelines don't specify a precise number for "low" diastolic pressure, most experts consider a reading below 60 mmHg as potentially problematic.
Causes of Low Diastolic Blood Pressure [1:50]
Several factors can cause low diastolic blood pressure, including medications like painkillers and antidepressants, as well as heart medicines used for high blood pressure. Other causes include severe infections, heart problems that reduce the heart's pumping ability, allergic reactions, sudden changes in body position, decreased blood volume, early pregnancy, nutritional deficiencies (like B12 and folic acid), and endocrine issues such as Addison's disease, low blood sugar, diabetes, and thyroid problems. Nerve damage from diabetes can also lead to low blood pressure, often without noticeable symptoms.
When Low Blood Pressure Becomes an Emergency [3:01]
While low blood pressure is not always an emergency, a sudden drop accompanied by symptoms like fainting, dizziness, blurred vision, rapid breathing, fatigue, lack of concentration, cold clammy skin, or dehydration requires immediate medical attention. The expert suggests calling 9-1-1 in such cases due to potentially life-threatening consequences.
Consequences of Untreated Low Diastolic Blood Pressure [3:46]
If low diastolic blood pressure is not addressed, it can lead to severe health issues, including stroke, heart attack, and kidney failure. These conditions can result in dangerous falls or car accidents if they occur while driving.
Treatments for Low Diastolic Blood Pressure [4:02]
Doctors may recommend several treatments for low diastolic blood pressure, including a diet higher in salt, increased fluid intake, medication adjustments, paying attention to body positions and movements, avoiding excess alcohol (which can cause dehydration), and monitoring blood pressure at home.
