Tuberculosis (TB) remains a significant global health threat, affecting millions of people annually. While TB primarily impacts the lungs, it can also spread to other parts of the body. With drug-resistant strains complicating treatment, understanding TB's causes, symptoms, and prevention strategies is essential. Transmission and High-Risk Factors TB is caused by the bacterium Mycobacterium tuberculosis , which spreads through airborne particles when an infected person coughs or sneezes. Individuals with weakened immune systems, such as those with HIV or malnutrition, are at a higher risk. Overcrowded living conditions and poor ventilation also increase the likelihood of transmission, particularly in areas with limited healthcare access. Symptoms of Active and Latent TB Active TB presents with persistent cough, chest pain, fever, night sweats, and weight loss. However, not everyone infected with TB bacteria develops symptoms. Latent TB, where the bacteria remain dormant,

  Coronary artery disease (CAD) is a global health issue that quietly affects millions. Often without symptoms until severe complications arise, CAD restricts blood flow to the heart, leading to heart attacks and other potentially life-threatening events. Understanding its risk factors, detection methods, and treatment options is essential in combating this “silent killer.” The Basics of Coronary Artery Disease CAD is caused by the build-up of plaque in the coronary arteries, which supply blood and oxygen to the heart. This plaque, composed of fat, cholesterol, calcium, and other substances, hardens, and narrows the arteries over time. Reduced blood flow deprives the heart of oxygen, causing symptoms such as chest pain (angina) and, in severe cases, heart attacks. This gradual development makes CAD challenging to detect early, underscoring the importance of regular health screenings for at-risk individuals. Advances in Early Detection: Coronary Calcium Scoring One of the most

Heart attacks are a significant health concern, affecting millions of people worldwide. Understanding the symptoms and risks associated with heart attacks is crucial for early detection and prompt medical intervention. In this guide, "Heart Attacks Unveiled: Recognizing Symptoms and Risks," we delve into the essential aspects of heart attacks, empowering you with knowledge for better heart health. Heart Attack vs. Cardiac Arrest Heart Attack A heart attack, also known as a myocardial infarction, occurs when the blood flow to a section of the heart muscle is blocked, usually due to the formation of a blood clot in one of the coronary arteries. These arteries are responsible for supplying oxygen and nutrients to the heart muscle. When blood flow is obstructed, the affected portion of the heart muscle begins to die, leading to severe consequences if not treated promptly. Cardiac Arrest Cardiac arrest, on the other hand, is a sudden and unexpected loss of heart function,
