Describe briefly:

Cardiovascular Diseases

Cardiovascular diseases are a leading cause of mortality globally. Hypertension (high blood pressure) is a prevalent condition, often asymptomatic but significantly increasing the risk of stroke, heart failure, and kidney disease. Coronary Artery Disease (CAD), characterized by plaque buildup in the arteries, can lead to angina (chest pain) and myocardial infarction (heart attack). Diagnosis involves ECG, echocardiography, and angiography. Treatment includes lifestyle modifications, medications (statins, ACE inhibitors, beta-blockers), and potentially interventions like angioplasty or bypass surgery.

Respiratory Diseases

Respiratory diseases encompass a wide range of conditions. Asthma is a chronic inflammatory airway disease causing recurrent episodes of wheezing, breathlessness, and chest tightness. Chronic Obstructive Pulmonary Disease (COPD), often linked to smoking, involves airflow limitation and progressive lung damage. Pneumonia, an infection of the lungs, can be caused by bacteria, viruses, or fungi. Diagnosis relies on physical examination, chest X-rays, and pulmonary function tests. Treatment includes bronchodilators, corticosteroids, antibiotics (for bacterial pneumonia), and oxygen therapy.

Gastrointestinal Diseases

Gastrointestinal disorders are common and diverse. Peptic Ulcer Disease (PUD) involves sores in the lining of the stomach or duodenum, often caused by Helicobacter pylori infection or NSAID use. Inflammatory Bowel Disease (IBD), including Crohn's disease and ulcerative colitis, causes chronic inflammation of the digestive tract. Liver cirrhosis is a late stage of scarring (fibrosis) of the liver caused by many forms of liver diseases and conditions, such as hepatitis and chronic alcoholism. Diagnosis involves endoscopy, colonoscopy, and imaging studies. Treatment varies depending on the condition, ranging from proton pump inhibitors (for PUD) to immunosuppressants (for IBD).

Endocrine Disorders

Diabetes mellitus, characterized by hyperglycemia, is a major endocrine disorder with significant long-term complications. Hypothyroidism, a deficiency of thyroid hormone, can cause fatigue, weight gain, and depression. Hyperthyroidism, an excess of thyroid hormone, can lead to anxiety, weight loss, and rapid heartbeat. Diagnosis involves blood tests to measure hormone levels. Treatment includes insulin or oral hypoglycemic agents (for diabetes), and thyroid hormone replacement or antithyroid medications (for thyroid disorders).

Neurological Disorders

Common neurological conditions include Stroke, caused by interruption of blood flow to the brain, leading to neurological deficits. Epilepsy is a chronic neurological disorder characterized by recurrent seizures. Parkinson's disease is a progressive neurodegenerative disorder affecting movement. Diagnosis involves neurological examination, brain imaging (CT scan, MRI), and electroencephalography (EEG). Treatment includes thrombolysis (for stroke), anticonvulsant medications (for epilepsy), and dopamine replacement therapy (for Parkinson's disease).

Infectious Diseases

General medicine also deals with a wide range of infectious diseases. Tuberculosis (TB), caused by Mycobacterium tuberculosis, primarily affects the lungs. Malaria, transmitted by mosquitoes, causes fever, chills, and anemia. Typhoid fever, caused by Salmonella typhi, is spread through contaminated food and water. Diagnosis involves microbiological tests and serological assays. Treatment includes antibiotics and supportive care.
