Alcohol intoxication (also known as "drunk" or "inebriated") occurs when the consumption exceeds the liver's capacity to metabolize it. The effects of alcohol intoxication differ from person to person depending on body weight, frequency of use and metabolism, however, common symptoms include: loss of inhibition, euphoric state, poor coordination, slurred speech, impaired balance, nausea and vomiting.
Alcohol overuse or abuse (commonly referred to as "alcoholism") is characterized by dependence on alcohol leading to repetitive use despite its effects on one's health or their activities of daily life, such as maintaining relationships or the ability to work. It typically includes periods of intoxication, where the alcohol content in the blood rises from recent consumption and causes mental status changes, poor coordination, nausea, vomiting, and even loss of consciousness and blackouts. It also includes periods of withdrawal which includes sweating, rapid heartbeat, hand tremors, problems sleeping, nausea and vomiting, hallucinations, restlessness and agitation, anxiety, and occasionally seizures.
An inflammation of the tissue lining the eyelids, called the conjuntiva due to a mild allergic reaction. The most common allergens are animal dander and plant pollens. The conjuntiva become red, swollen, itchy and often tear up excessively.
An allergic reaction is an abnormal response of the immune system to some type of foreign substance. The substance that triggers the allergic reaction is called an allergen. Exposure to the allergen for the very first time does not produce any symptoms. The reaction starts following an additional exposure once the immune system has had a chance to form antibodies to the allergen. Each additional future interaction with the allergen may trigger a more dramatic response. Allergic reactions can range from simple sneezing or rashes to difficulty breathing, swelling, anaphylactic shock or death.
Allergic rhinitis is inflammation of the mucus membranes of the nose and upper respiratory tract resulting in sneezing, runny nose, congestion, nasal itching, eye redness and possibly eyelid swelling . This usually occurs after exposure to substances called allergens like pollen, dust, animal dander and others. Allergic rhinitis is the result of a hypersensitivity reaction to these airborne allergens. This is not a life-threatening disease if it is not accompanied by asthma attacks or angioedema (abnormal swelling of a body part). Most cases of this condition (80%) are diagnosed by the age of 20. It is estimated that 1 in 4 people have experienced this condition. This condition can occur with or without a rash.

Alopecia areata is a hair loss caused by an autoimmune response, or the body's own immune system abnormally attacking normal tissues of the body. In this case, it is the parts of the skin where hair grows. This can cause sudden loss of patches of hair on the scalp and sometimes other parts of the body. Most patients will have the hair grow back, but this may take months. Approximately 50 percent of people with mild alopecia areata recover within a year; however, most people will experience more than one episode during their lifetime. The condition can develop at any age, although most people develop alopecia areata for the first time before the age of 30.
Altered Mental Status is a sudden change in mental functioning. It has many causes including infection, adverse drug reactions, Alzheimer's, low blood pressure, brain tumor, stroke, metabolic disorders, or hydrocephalus.
Altitude sickness occurs when you travel or ascend to high altitudes too quickly. As a result, your body isn't able to get enough oxygen from the air at high altitudes. This causes symptoms such as nausea, headache, fluid in the lungs, confusion and coma. Factors such as drinking lots of alcohol during your ascent or not drinking enough fluids can predispose you to developing altitude sickness. It occurs most often in people who are not accustomed to high altitudes travel rapidly from lower altitudes to altitudes of 8000 ft or higher. The main treatment is to immediately descend to a lower altitude in order to prevent dangerous complications such as swelling of the brain or fluid in your lungs.
Painless and sudden onset of vision loss caused by a blockage of the artery that provides blood flow to the retina of the eye. Blockage of the retinal artery is usually due to a dislodged piece of plaque (fat and calcium deposits) that has built up in the carotid arteries of the neck that supply blood to the brain. This condition is a risk factor for future strokes, myocardial infarction (heart attack) and permanent vision loss.
An anal fissure or rectal fissure is a break or tear in the skin of the anal canal. Anal fissures may present as bright red anal bleeding on toilet paper after wiping or sometimes in the toilet. If acute they may cause pain after defecation but with chronic fissures pain intensity is often less. Being constipated or having hard stools can lead to this condition.
