Sudden Drop in BP or Sugar: What to Do?
A sudden fall in blood pressure or blood sugar levels can be worrying and should never be taken lightly. At Mulshi Speciality Hospital, we regularly see patients reporting symptoms such as dizziness, weakness, excessive sweating, or sudden fainting due to unexpected changes in BP or sugar levels. If timely care is not given, these conditions may lead to serious health complications. Recognising the early warning signs and knowing the right steps to take can help avoid emergencies and safeguard your health.
Understanding BP and Blood Sugar Levels:
Blood pressure and blood sugar play a crucial role in maintaining overall health and body function.
- Normal blood pressure is generally considered to be around 120/80 mmHg.
- Normal blood sugar levels depend on whether the test is done fasting or after meals and should remain within the limits recommended by your doctor.
A sudden decline in either BP or sugar levels can interrupt the supply of oxygen and energy to important organs, especially the brain, resulting in uncomfortable and sometimes dangerous symptoms.
What Is a Sudden Drop in BP (Hypotension)?
Hypotension refers to a condition where blood pressure falls below the normal range, leading to reduced blood circulation to vital organs.
Common Causes of Low Blood Pressure:
- Lack of adequate fluid intake causing dehydration
- Standing up suddenly, particularly in older adults (postural hypotension)
- Long-term illness or high fever
- Heart-related medical conditions
- Side effects of certain medications
Exposure to extreme heat or excessive physical exertion
What Is a Sudden Drop in Blood Sugar (Hypoglycaemia)?
