- Why You Need To Stop Ignoring CataractA cataract is opacity or cloudiness of the lens of the eye that may cause the loss of visual acuity. In the cataract color and structure of the lens is destruct and change in the milky white colors. Cataracts rank as it were behind arthritis and heart disease as a leading cause of disability in more seasoned grown-ups. Cataracts influence about 20.5 million Americans who are 40 a long time of age or more seasoned or approximately one in every six individuals in this age run. By age 80, more than half of all Americans have cataracts. Concurring to the World Health Organization, cataract is the driving cause of visual impairment within the world.
- Glaucoma A Silent Cause of Vision LossGlaucoma is a group of eye disease which is characterized by increase intraocular pressure. Increase IOP damages the Optic nerve and nerve fiber layer. A glaucoma is a group of ocular conditions characterized by optic nerve damage. The optic nerve damage is related to the intraocular pressure (IOP) caused by congestion of aqueous humor in the eye. There is a range of pressures that have been considered “normal” but that may be associated with vision loss in some patients. Glaucoma is more prevalent among people older than 40 years of age, and the incidence increases with age. It is also more prevalent among men than women and in the African American and Asian populations. There are two types of glaucoma Primary glaucoma which include Open angle glaucoma and angle closer glaucoma, and another one is Secondary glaucoma.
Biochemistry
Transportation through the cell membrane
Transportation of substances across the cell membrane is essential to the life of a cell. Various substances must have moved into cells because they help to support metabolic reactions. This process is classified into two process these are Passive mechanism and Active mechanism.

Cancer Causes, Types, Symptoms and Signs
Cancer: Everything you want to know!
Cancer is a disease of cell in which normal mechanisms of control of growth and proliferation are disturbed. Cancer is a group of cells that grows out of control, taking over the function of affected organs or it is a group of diseases characterized by uncontrolled cellular growth with local tissue invasion at systemic metastasis. It is a disease process that begins when abnormal cells are transformed by a genetic mutation of cellular DNA.
Breast cancer: Types, Pathophysiology, Cancer Stages, Symptoms, Investigation, Management
Breast cancer is cancer that forms in the cells of the breast.
After skin cancer breast cancer is the most common cancer diagnosed in women. Breast cancer is a disease that occurs when cells in breast tissue change or mutate and keep reproducing, these abnormal cells usually cluster together to form a tumor. A tumor is cancerous or malignant when these abnormal cells invade other parts of the breast.
Digestive System
Hiatus Hernia: Causes, Types, Diagnosis, Treatment, Management
A type of hernia in which part of the stomach protrudes up through the esophageal opening of the Diaphragm. Hiatus hernia is an anatomical abnormality in which the part of the stomach protrudes up through the diaphragm into the chest. The exact cause is unknown. It may be due to, Increased pressure within the abdominal cavity. It may be due to – Heavy lifting, Pregnancy, Ascites, Frequent or hard coughing, Boilent vomiting, Starving etc…
Gastritis or Stomach Inflammation: Types, Etiology, Clinical Feature, Diet Management
Inflammation of the gastritis mucus membrane is called Gastritis. It may occur as a short episode or may be of long duration. clinically gastritis is classifies into types these are Acute Gastritis and Chronic Gastritis. on the basis of histology or endoscopic appearance classified into three types those are hemorrhagic , Non-Erosive and Specific gastritis.
Gastroesophageal Reflux Disease (GERD): Symptoms, Causes, Treatment
Gastroesophageal Reflux Disease (GERD) is reflux (return) of gastric content (mainly acid) towards the mouth resulting in esophageal tissue damage. This is a chronic disease that occurs when stomach acid (HCL) or bile flows into the food pipe and irritates the inner lining. Gastroesophageal Reflux Disease (GERD) also known as Acid Reflux.

Corona Virus or COVID-19: Everything you want to know about!
Coronavirus disease or COVID-19 is an infectious disease caused by a newly discovered Coronavirus. which is spreading all over the world too fast. Most of the developed and developing countries are already affected by a coronavirus and now taking precautions to stop the spread of coronavirus. The incidence and types of coronavirus are given below. The most common and less common symptoms of coronavirus and its precaution are described.
Heart
The varicose vein or Varicosity
The varicose vein or varicosity is an abnormally dilated, tortuous superficial vein caused by an incompetent venous valve.
varicose veins are permanently distended veins that develop from the loss of valvular competence faulty valves elevated venous pressure causing distention and tortuosity of superficial veins.
Aneurysm: Causes, Symptoms, Diagnosis, and Treatment
The aneurysm is defined as a permanent localized dilation, stretching, and ballooning of an artery or blood vessels to around 50% increases in the size. The exact cause of aneurysm is unknown. Aneurysm is classified into 7 types according to location, Etiological factor, appearance, saccular, fusiform, dissecting, and false aneurysm.
Rheumatic Heart Disease: Sign and Symptoms, Pathophysiology
Rheumatic Heart Disease usually affects the children and it is still the most common cause of acquired heart disease in childhood and adolescence. R.H.D. is usually affected by 5-15 years of the child. 1-2 case/lakh in developed countries. 100 case/ lakh in developing countries. 3% of people affected after the beta-hemolytic streptococci infection.

Skeletal System
Osteoporosis Causes, Symptoms, Risk factor, and Treatment
Abnormal rarefaction of bone which may be idiopathic or secondary to other conditions.
This disorder leads to the thinning of skeletal and decreases precipitation of lime salt.
Osteoporosis is defined as a systemic skeletal disease characterized by low bone mass and micro-architectural determination of bone tissue that leads to increase bone fragility and susceptibility to fracture or breakdown (hips, vertebrae, forearm).
Urinary System
Acute Kidney Injury [ Acute Renal Failure] or kidney failure
Acute kidney injury Previously called Acute Renal Failure is an abrupt loss of kidney functions that develops within 7 days.
It is characterized or manifested by decrease glomerular filtration rate, level of serum creatinine, and urea nitrogen rise and oliguria or anuria.
Its cause is numerous. Generally, it occurs because of damage to kidney tissue caused by decreased blood flow (ischemic kidney), low blood pressure or hypotension, exposure to substance harmful to the kidney, inflammatory process, or an obstruction of the urinary tract.
