Generally common cold is viral infection of the upper respiratory tract that affects the nose, throat, sinuses, larynx, and sometimes the lungs. Different kinds of rhinovirus and corona virus are the most common causes. These viruses are easily transmitted through contact with the secretions of infected people. Once the virus enters the body, it multiplies in the cells (often at the back of the nose) and causes an inflammatory response that produces characteristic symptoms such as excessive mucus (probably in an attempt to rid the body of the virus) and swollen airways.

A heart attack usually occurs when a blood clot blocks the flow of blood through a coronary artery — a blood vessel that feeds blood to a part of the heart muscle. The interrupted blood flow that occurs during a heart attack can damage or destroy a part of the heart muscle.
A heart attack is a life-threatening event in which the supply of blood and oxygen to part of the heart is blocked. Many heart attack victims wait two hours or more after their symptoms begin before they seek medical help. This delay can result in death or lasting heart damage. Quickly seeking treatment for a heart attack may help prevent much or all of the permanent damage a heart attack can cause. Continue reading
Allergy is the general non medical term for a hypersensitivity reaction. It results when the body’s immune system overreacts to a substance that is normally harmless. The substance, which is referred to as an allergen, could be anything from the pollen of a specific tree to a particular ingredient in a medication. It could be a puppy’s dander or a food such as peanuts. While not everyone experiences allergies, some people are allergic to one specific thing, while others suffer a wide variety of different reactions to different allergens.
Two of the most common types of allergies are seasonal outdoor allergies (seasonal allergic rhinitis) and year-round indoor allergies (perennial allergic rhinitis). Those who sneeze and sniffle at certain times of the year can blame pollen for their symptoms. Tree pollen flourishes in the spring, while grass and weed pollen takes over in late summer and early autumn. Indoor allergens like dust, mould, mildew, and animal dander can irritate eyes, noses, and throats all year round. Continue reading

It is the third most common mental illness, affecting more than 200 million people in the world. Other facts and statistics about alcohol dependence include its pattern of afflicting about 10% of women and 20% of men.
Alcoholism formerly called alcohol dependence or alcohol addiction is the more severe end of the alcohol use disorder spectrum. Continue reading
Brain cells need a constant supply of fresh oxygen and glucose in order to function properly. A stroke or CVA (or cerebrovascular accident) refers to the condition where a blood clot or a ruptured artery or blood vessels prevents the normal flow of blood to a particular area of the brain. When this happens, the lack of oxygen and glucose causes the brain cells to die and results in brain damage that can affect mechanisms such as movement, speech, and memory. Continue reading
People who are passing a difficult time with lots of problems like depression, anxiety, bipolar disorder, schizophrenia, frustration, family problems are prone to suicidal attempt. Don’t be crazy! Life is more valuable than daily complexities.
You’re not alone; many of us have had suicidal thoughts at some point in our lives. Feeling suicidal is not a character defect, and it doesn’t mean that you are crazy, or weak, or flawed.

But with time and support, you can overcome your problems and the pain and suicidal feelings will pass. Continue reading
Typhoid, also known as typhoid fever, occurs due to infection by the salmonella typhi bacteria. It spreads through ingestion of contaminated food and water. It can also spread through close contact with someone who has the infection. Typhoid leads to symptoms such as headache, abdominal pain, fever and diarrhea. The symptoms are alleviated with the help of antibiotic medications. Typhoid, in some cases, may result in serious life-threatening complications. There are vaccines available for typhoid. While the new vaccines for typhoid do offer considerable protection they are not guaranteed to work, but can considerably lower the risks of infection. Individuals who are travelling to regions where typhoid fever is widespread are advised avail of the vaccine. Continue reading
Tooth decay is a degenerative oral health condition that results from the breakdown of tooth enamel. The destruction of tooth structure associated with decay can lead to the development of holes in the teeth, more commonly referred to as cavities. It is the process that results in a cavity (dental caries). It occurs when bacteria in your mouth make acids that eat away at a tooth. If not treated, tooth decay can cause pain, infection, and tooth loss.
You can easily prevent tooth decay by brushing and flossing your teeth regularly, seeing your dentist for teeth cleaning and checkups, and avoiding foods those are high in sugar. Continue reading
Sweating occurs when the sweat glands in our skin secrete a salty fluid called sweat, or perspiration. Sweating is a normal phenomenon that serves to cool your body, often in hot or humid environments or when you exercise.
More sweating may be a symptom of an underlying disease, disorder or condition. The medical term for excessive sweating is hyperhidrosis. Hyperthyroidism (overactive thyroid) and hypoglycemia (low blood sugar) are just two of many conditions that may cause excessive sweating. Continue reading
Piles or hemorrhoids is a painful condition of inflammation and swelling that affects the veins around the anus or rectum. Although the pain can often be unbearable, in most cases the condition itself is not threatening. The condition is characterized by severe pain, especially with the passage of stools, and in some cases there may also be bleeding. Hemorrhoids may disappear by themselves without any treatment or may become itchy or inflamed and cause a significant amount of discomfort. Piles can also recur and cause internal bleeding and in some cases there may be a need for surgical intervention.
There are two main types of piles internal piles that develop inside the anus and rectum (and can be felt and not seen) and external piles that occur outside and around the anal opening (that can be easily seen). When an internal hemorrhoid protrudes outside the anus, it is known as a prolapsed hemorrhoid. It is also possible that you may develop both types of piles at the same time. Internal hemorrhoids are rarely painful and you may not even be aware of them. External hemorrhoids however can be painful and uncomfortable and may bleed along with the itching and inflammation.
