Bronchitis is an inflammation of the bronchial tubes, which carry air to and from the lungs. It is often caused by viral infections, but bacterial infections and environmental factors like smoking or pollution can also trigger it. Bronchitis can be classified as either acute or chronic, depending on the duration and frequency of symptoms. Signs & Symptoms The symptoms of bronchitis can vary depending on whether the condition is acute or chronic: Acute Bronchitis : Cough : Often with mucus production. Fatigue . Shortness of breath . Wheezing . Chest discomfort . Low-grade fever (in some cases). Chronic Bronchitis (part of Chronic Obstructive Pulmonary Disease or COPD): Chronic cough with mucus for at least three months in two consecutive years. Wheezing and shortness of breath . Frequent respiratory infections . Anatomy Affected Bronchitis affects the bronchial tubes , which are part of the lower respiratory tract. These tubes become inflamed and narrow, leading to difficulty in ...

Benign Prostatic Hyperplasia (BPH) is a non-cancerous enlargement of the prostate gland that commonly occurs as men age. It can cause urinary symptoms that affect quality of life, but it does not increase the risk of prostate cancer. BPH is highly prevalent in older men, especially those over the age of 50. Signs & Symptoms The symptoms of BPH are primarily urinary-related due to the enlargement of the prostate, which presses on the urethra: Frequent urination : Especially at night (nocturia). Urgency : A strong, urgent need to urinate. Weak urine stream : Difficulty starting or maintaining urination. Incomplete bladder emptying : Feeling like the bladder is not fully emptied. Straining to urinate : A feeling of needing to push to get the urine out. Dribbling : Leakage after finishing urination. Anatomy Affected BPH affects the prostate gland , which is located below the bladder and surrounds the urethra in men. As the prostate enlarges, it presses on the urethra, which interferes ...

Atherosclerosis is a chronic disease characterized by the hardening and narrowing of arteries due to plaque buildup. This condition is a leading cause of cardiovascular diseases, such as heart attacks and strokes, and progresses silently over decades before symptoms emerge.

Acute Respiratory Distress Syndrome (ARDS) is a severe and sudden lung condition that results in fluid buildup in the alveoli, preventing oxygen from adequately reaching the bloodstream. Often seen in critically ill or injured individuals, ARDS requires immediate medical intervention to prevent fatal outcomes. Signs & Symptoms The onset of ARDS is often rapid, and symptoms can include: Severe shortness of breath. Rapid breathing (tachypnea). Low blood oxygen levels (hypoxemia). Extreme fatigue and confusion. Bluish discoloration of the skin or lips (cyanosis). Chest pain or discomfort, especially during breathing. Potential respiratory failure requiring mechanical ventilation. Anatomy Affected ARDS primarily affects the lungs , specifically the alveoli (tiny air sacs responsible for gas exchange). In ARDS, inflammation causes fluid to leak into these air sacs, making it difficult for oxygen to pass into the bloodstream. Other systems, such as the heart and brain, can be indirectly ...

Acute Renal Failure (ARF), also known as Acute Kidney Injury (AKI), is a sudden and rapid loss of kidney function. This condition requires immediate medical attention as it can lead to severe complications or even death if left untreated. Signs & Symptoms ARF often develops quickly, and its symptoms can include: Decreased urine output, though occasionally urine output remains normal. Fluid retention leading to swelling in the legs, ankles, or feet. Fatigue and weakness. Shortness of breath. Confusion or disorientation. Nausea and vomiting. Chest pain or pressure due to fluid accumulation around the heart. Seizures or coma in severe cases. Anatomy Affected The kidneys are primarily affected in ARF. These vital organs, located on either side of the spine below the rib cage, are responsible for filtering waste products and excess fluids from the blood. ARF disrupts this critical filtration process, potentially causing systemic effects throughout the body. Causes/Transmission ARF is no...

Post-Inflammatory Hyperpigmentation (PIH) is a common skin condition characterized by the darkening of skin in areas where inflammation or injury has occurred. It often results from skin trauma, such as acne, burns, eczema, or medical procedures. While not harmful, PIH can affect self-esteem and confidence, making it a concern for many individuals seeking dermatological care. What is PIH? PIH occurs when the skin produces excess melanin, the pigment responsible for skin color, in response to inflammation or damage. This overproduction results in flat, darkened patches or spots that can range from light brown to black, depending on your natural skin tone. PIH is more common in individuals with darker skin types (Fitzpatrick skin types IV-VI) due to their higher baseline melanin levels. Causes of PIH Skin Injuries : Cuts, scrapes, or burns can leave behind dark spots during the healing process. Acne : Inflammatory acne, such as cysts or pustules, is a leading cause of PIH. Eczema and Ps...

Knee pain can be debilitating, often stemming from injuries to the meniscus — the crescent-shaped cartilage that cushions and stabilizes the knee joint. A meniscectomy is a surgical procedure to remove the damaged part of the meniscus, alleviating pain and restoring function. This blog post delves deep into the anatomy of the meniscus, causes of injury, indications for surgery, the procedure itself, and what to expect during recovery. What Is the Meniscus? The meniscus is a vital structure located between the femur (thighbone) and tibia (shinbone). Each knee has two menisci: Medial Meniscus : Found on the inner side of the knee, it absorbs more weight and is more prone to injury. Lateral Meniscus : Found on the outer side, it is more mobile and less commonly injured. Function : Shock Absorption : Protects bones from impact during activities like walking or running. Stabilization : Prevents excessive movement in the knee joint. Load Distribution : Ensures even distribution of body weig...
