Hair loss is one of the most common physical conditions, especially in older men and women. On average, the adult head loses approximately 100 hairs every day. 90% of the hair on the scalp is growing at all times. There are a number of factors that might result in hair loss, including age, disease, and the like.

While hearing loss is usually associated with aging, partial or total hearing loss can affect people of all ages if it occurs due to inner ear or nerve damage, among other causes. In fact, two-thirds of all people with hearing loss are aged below 65 years. In most people, using a hearing aid can help treat the issue, or it can be treated with surgery.

An uncomfortable burning sensation in the chest, right behind the breastbone, is common in many, especially after a large meal. Experiencing these heartburns occasionally is not a matter of concern as it does not lead to health problems. However, when these heartburns become frequent, it can be referred to as gastroesophageal reflux disease (GERD).

Immune system disorder causes the immune system to act abnormally — either more than usual or less than usual. In case the immune system is acting more than it is supposed to, it identifies tissues of the body as external bodies and attacks them. Immune system deficiency, on the other hand, causes a drop in the ability of the body to fight external bodies, thereby resulting in exposure to infections.

Heart disease is a cluster of diseases that affect the heart. The different diseases that come under this cluster are various blood vessel-related conditions, like coronary artery disease, congenital heart problems, and heart problems related to the rhythms or arrhythmias. The terms heart disease and cardiovascular disease are often used interchangeably.

Joint conditions refer to any condition or disease that affects the joints. Arthritis is the most well-known and commonly occurring joint disease, while there are several others that impact the health of individuals across the world. Diseases related to the joints can be both short-lived or they can turn chronic and require surgery and other serious treatment.
