 Anemia – Causes, Symptoms, and Treatment


What is Anemia?

Anemia is a health condition in which the number of healthy red blood cells or the amount of hemoglobin in the blood is lower than normal. Hemoglobin is the protein in red blood cells that carries oxygen to all parts of the body. When hemoglobin levels are low, the body’s organs and tissues do not get enough oxygen, leading to tiredness and weakness.

Causes of Anemia


There are several reasons why anemia can occur, including:


1. Iron Deficiency – The most common cause, often due to poor diet, blood loss, or inability to absorb iron properly.


2. Vitamin Deficiency – Lack of Vitamin B12 or folate can reduce red blood cell production.


3. Blood Loss – Heavy periods, surgery, injury, or internal bleeding.


4. Chronic Diseases – Kidney disease, cancer, or other long-term illnesses.


5. Bone Marrow Problems – Disorders that affect blood cell production, such as aplastic anemia or leukemia.

Symptoms of Anemia

Common signs and symptoms include:

Persistent fatigue and weakness

Pale or yellowish skin

Dizziness or lightheadedness

Shortness of breath

Rapid or irregular heartbeat

Cold hands and feet

Headaches


---


Treatment for Anemia

Treatment depends on the underlying cause:

Iron-deficiency anemia – Iron-rich diet (spinach, red meat, lentils) and iron supplements.


Vitamin-deficiency anemia – Vitamin B12 and folate supplements or injections.


Anemia due to blood loss – Treating the source of bleeding and restoring blood levels.


Chronic disease-related anemia – Managing the underlying illness.

Prevention Tips

Eat a balanced diet rich in iron, vitamin B12, and folate.


Include foods like leafy greens, beans, nuts, red meat, eggs, and fortified cereals.


Avoid excessive tea or coffee after meals (as they reduce iron absorption).


Go for regular health check-ups to monitor hemoglobin levels.

Conclusion

Anemia is a common but often overlooked health issue. Early detection and proper treatment can restore energy levels and prevent serious complications. Maintaining a healthy diet and lifestyle is the key to preventing anemia ---

 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...

 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...

 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...
