Liver, muscles, and fat tissue : These organs are impacted due to reduced ins...

Cushing Syndrome is a rare condition caused by prolonged exposure to high levels of cortisol, a hormone produced by the adrenal glands. It can result from the use of corticosteroid medications or from tumors in the pituitary or adrenal glands that produce excessive cortisol.

Congestive heart failure (CHF) is a chronic condition in which the heart is unable to pump blood effectively to meet the body's needs. The term “congestive” refers to the accumulation of fluid in the body, particularly in the lungs and extremities, which is a hallmark of the disease. Over time, the heart's ability to circulate blood diminishes, leading to a buildup of fluid in the lungs, liver, and other tissues. Signs & Symptoms CHF often presents with a range of symptoms, which can vary depending on the severity of the condition and which side of the heart is affected (right or left ventricle). Common symptoms include: Shortness of breath (dyspnea), especially during physical activity or when lying flat. Fatigue and weakness, due to inadequate blood flow to the body’s tissues. Swelling (edema) in the ankles, legs, or abdomen caused by fluid retention. Rapid or irregular heartbeat (arrhythmia), as the heart tries to compensate for its reduced ability to pump blood. Co...

Colorectal cancer (CRC) , also known as colon cancer or rectal cancer, refers to cancer that begins in the colon or rectum , parts of the large intestine. It typically starts as polyps , which are small clumps of cells that can become cancerous over time. This disease is the third most common cancer worldwide and one of the leading causes of cancer-related deaths. Signs & Symptoms In the early stages of colorectal cancer, patients may not experience noticeable symptoms. As the cancer progresses, the following symptoms may develop: Change in bowel habits : This includes diarrhea, constipation, or the feeling that the bowel doesn't empty completely. Blood in the stool : Either visible as red blood or in the stool's appearance (dark and tarry). Abdominal discomfort : Cramps, bloating, or pain in the abdomen. Unexplained weight loss : Due to poor absorption of nutrients. Fatigue : Often resulting from anemia due to chronic blood loss. Nausea and vomiting : This can occur espe...

Chronic Renal Failure, or Chronic Kidney Disease (CKD) , is a progressive loss of kidney function over time. The kidneys are vital organs responsible for filtering waste and excess fluid from the blood, which is then excreted in the urine. When the kidneys lose their ability to perform this function, waste and fluid build up in the body, leading to a range of complications. CKD is typically a gradual process, often occurring over many years, and can eventually lead to kidney failure. Signs & Symptoms The symptoms of chronic kidney disease may not be noticeable in the early stages. As the disease progresses, patients may experience the following: Fatigue and weakness Swelling (edema) in the legs, ankles, and feet due to fluid retention Shortness of breath and difficulty breathing Decreased urine output Blood in the urine (hematuria) or foamy urine High blood pressure (hypertension) Nausea and vomiting Loss of appetite Itchy skin Persistent bad breath (uremic fetor) Anemia due...

Chronic Obstructive Pulmonary Disease (COPD) is a progressive lung disease that makes breathing difficult. It is characterized by a long-term reduction in airflow and can cause serious complications if not managed properly. COPD includes two main conditions: chronic bronchitis and emphysema . These conditions are often caused by long-term exposure to harmful substances like cigarette smoke, air pollution, or chemical fumes, which lead to inflammation and narrowing of the airways in the lungs. Signs & Symptoms COPD develops gradually and may not show noticeable symptoms in its early stages. As the disease progresses, symptoms become more pronounced and include: Shortness of breath (especially during physical activity) Chronic cough (often accompanied by mucus) Wheezing (a whistling sound when breathing) Chest tightness Frequent respiratory infections Fatigue and overall weakness Unintentional weight loss (in severe cases) The severity of symptoms can vary and typically worsens...
