Liver Function Tests (LFT) :

LIVER FUNCTION TEST:

 LFT stands for Liver Function Test, which is a blood test that measures the levels of various enzymes and proteins produced by the liver. These tests are performed to assess the overall health and function of the liver and to diagnose and monitor liver diseases.


Role of liver:

The liver plays a crucial role in metabolism, detoxification, and production of important proteins. When there is an increase in LFT results, it typically indicates some form of liver damage or dysfunction. Here are a few potential causes:

1. Hepatitis: Viral hepatitis, such as hepatitis A, B, or C, can cause inflammation of the liver, leading to elevated liver enzymes.

2. Alcoholic liver disease: Prolonged and excessive alcohol consumption can damage the liver and elevate LFT levels.

3. Non-alcoholic fatty liver disease (NAFLD): This condition occurs when excess fat accumulates in the liver, leading to inflammation and liver damage.

4. Medications: Certain medications, such as statins, acetaminophen, or some antibiotics, can cause liver enzyme levels to rise.

5. Autoimmune disorders: Conditions like autoimmune hepatitis, primary biliary cirrhosis, or primary sclerosing cholangitis can result in liver inflammation and elevated LFTs.

6. Gallbladder disease: Issues with the gallbladder, such as gallstones or inflammation (cholecystitis), can affect liver enzyme levels.

It's important to note that an increase in LFT levels does not necessarily indicate a specific disease or condition. Further evaluation, including a thorough medical history, physical examination, and additional tests, is needed to determine the underlying cause and appropriate treatment.

Elevated LFT result:

If a patient has elevated LFT results, the potential problems or symptoms they may experience depend on the underlying cause. Common signs and symptoms of liver dysfunction or damage include:

- Jaundice: Yellowing of the skin and eyes

- Fatigue and weakness

- Abdominal pain or swelling

- Nausea and vomiting

- Loss of appetite

- Dark urine

- Pale or clay-colored stools

- Itchy skin

- Easy bruising or bleeding


It's crucial for individuals with elevated LFTs to consult with a healthcare professional who can evaluate their specific case, conduct further investigations if necessary, and provide appropriate treatment and management strategies.

Chronic obstructive pulmonary disease (COPD):   COPD is a progressive lung disease that causes airflow limitation and breathing difficulties. Causes: The primary cause of COPD is long-term exposure to irritating gases or particles, most commonly from cigarette smoke. Other factors that contribute to COPD include exposure to air pollution, occupational dust and chemicals, genetic factors (such as alpha-1 antitrypsin deficiency), and respiratory infections during childhood. Prevention: Prevention strategies for COPD mainly focus on avoiding exposure to risk factors. The most crucial preventive measure is to quit smoking and avoid secondhand smoke. Reducing exposure to indoor and outdoor air pollution, workplace chemicals, and dust can also lower the risk. Proper vaccination against respiratory infections, such as influenza and pneumonia, is recommended. Symptoms: COPD symptoms typically develop slowly over time and worsen as the disease progresses. Common symptoms include persistent ...

Angina Pectoris or Heart pain/ chest pain: causes,symptoms,prevention and treatment

Angina or Heart Pain: Angina is a condition characterized by chest pain or discomfort that occurs when the heart muscle doesn't receive enough oxygen-rich blood. It is usually a symptom of an underlying heart condition, most commonly coronary artery disease (CAD), where the blood vessels supplying the heart become narrowed or blocked by a buildup of fatty plaques. Causes: 1. Coronary artery disease (CAD): The primary cause of angina is the narrowing of the coronary arteries due to plaque buildup, reducing blood flow to the heart. 2. Spasm of coronary arteries : In some cases, the coronary arteries may spasm and temporarily restrict blood flow to the heart, causing angina. 3. Other factors: Angina can also be triggered by conditions such as aortic valve disease, high blood pressure, heart failure, or anemia. Symptoms: The most common symptom of angina is chest pain or discomfort. The pain is often described as a squeezing, pressure, heaviness, or tightness in the chest. Other symp...

Renal Failure: causes,prevention and treatment

Renal Failure or Kidney Failure: Renal failure, also known as kidney failure, is a condition in which the kidneys lose their ability to function properly , resulting in the accumulation of waste products and fluids in the body. It can be classified into two main types: acute renal failure (ARF) and chronic renal failure (CRF). Causes of Renal Failure: 1. Acute Renal Failure: ARF can occur due to factors such as severe dehydration, reduced blood flow to the kidneys, kidney injury or trauma, certain medications, infections, or conditions like acute glomerulonephritis or acute tubular necrosis. 2. Chronic Renal Failure: CRF develops gradually over time and is often caused by underlying conditions that damage the kidneys, such as diabetes, high blood pressure (hypertension), chronic glomerulonephritis , polycystic kidney disease, recurrent kidney infections, or prolonged use of certain medications. Prevention of Renal Failure: 1. Manage underlying conditions: Control diabetes and hyp...
