 Blood Pressure – An Essential Vital Sign


What is Blood Pressure?

Blood pressure is the force exerted by circulating blood on the walls of the arteries. It’s an important indicator of heart health and overall circulation.


Think of it like water flowing through a garden hose — if the pressure is too high, the hose can get damaged; if it’s too low, the water won’t reach the plants properly. In your body, the “hose” is your arteries, and the “water” is your blood.

How is Blood Pressure Measured?


Blood pressure is measured in millimeters of mercury (mmHg) and is recorded as two numbers:


1. Systolic Pressure (upper number) – the pressure in the arteries when the heart beats and pumps blood.



2. Diastolic Pressure (lower number) – the pressure in the arteries when the heart relaxes between beats.




Example: 120/80 mmHg (spoken as “120 over 80”).

Normal & Abnormal Ranges


Category Systolic (mmHg) Diastolic (mmHg)


Normal < 120 < 80

Elevated 120–129 < 80

High BP Stage 1 130–139 80–89

High BP Stage 2 ≥ 140 ≥ 90

Hypertensive Crisis > 180 > 120

Why is Blood Pressure Important?

Maintaining a healthy blood pressure:


Ensures oxygen and nutrients reach your organs.


Reduces strain on the heart and blood vessels.


Prevents serious health problems like heart attack, stroke, and kidney disease.

Factors Affecting Blood Pressure


Lifestyle: Diet high in salt, lack of exercise, smoking, alcohol.


Medical conditions: Diabetes, kidney disease, hormonal issues.


Stress: Emotional and mental pressure can temporarily raise BP.


Age & Genetics: Older age and family history increase risk.


---


Tips to Maintain Healthy Blood Pressure


Eat a balanced diet rich in fruits, vegetables, and low-sodium foods.


Exercise regularly (30 minutes a day).


Avoid smoking and limit alcohol.


Manage stress with meditation, prayer, or hobbies.


Monitor your blood pressure regularly.

✅ Key Takeaway:

Blood pressure is a silent but powerful indicator of your health. Keep it in check through a healthy lifestyle, regular monitoring, and timely medical care.

 Typhoid Fever — Overview for Medical Students Definition: Typhoid fever is an acute, systemic infection caused by the bacterium Salmonella enterica serotype Typhi (S. Typhi). It is transmitted primarily via the fecal-oral route and is common in areas with poor sanitation. If untreated, it can be life-threatening --- Etiology (Cause) Causative organism: Salmonella Typhi (gram-negative bacillus, motile, non-spore forming). Source: Humans are the only reservoir. Transmission: Contaminated food or water, direct contact with an infected person or chronic carrier. --- Pathophysiology 1. Ingestion of S. Typhi → survives gastric acid → reaches small intestine. 2. Invades intestinal mucosa → enters lymphatics → bloodstream. 3. Disseminates to liver, spleen, bone marrow → causes systemic infection. 4. Organisms re-enter intestine via bile → can cause intestinal ulceration. --- Incubation Period Usually 7–14 days (range: 3–60 days depending on dose of bacteria). --- Clinical Features Week-wi...

 Hemoglobin What is hemoglobin ? Hemoglobin – Structure, Function, and Importance Introduction Hemoglobin is a protein found in red blood cells (RBCs) that plays a vital role in transporting oxygen from the lungs to all tissues of the body and carrying carbon dioxide back to the lungs for exhalation. It is essential for maintaining proper oxygen levels in the body and supporting life. --- Structure of Hemoglobin Hemoglobin is made up of iron and a protein called globin. It has four protein chains (two alpha and two beta chains), each containing a heme group. The heme group contains an iron atom that binds to oxygen, giving hemoglobin its red color. --- Normal Hemoglobin Levels The normal hemoglobin levels vary depending on age, gender, and health condition: Men: 13.8 – 17.2 g/dL Women: 12.1 – 15.1 g/dL Children: 11 – 16 g/dL Pregnant women: 11 – 12 g/dL --- Low Hemoglobin (Anemia) Low hemoglobin levels can lead to a condition called anemia, which may cause symptoms such as: Fatigue...
