Whenever an individual suffers from some chronic and life threatening disease the quality of life of both sufferer and the caregiver are impaired. What is life threatening disease? Life threatening disease is any disease that could lead to the death of an individual. Now a days, the prevalence of life threatening diseases is rising significantly. The diseases are becoming common and leading causes of deaths in developing and developed countries.

There are many diseases which are life threatening and common at the same time. Some of the diseases are as follows:
1. Coronary heart disease
Coronary heart disease is one of the most common diseases in both developing and developed countries. It is a chronic disorder which is responsible for a large number of deaths each year. Coronary heart disease, also known as coronary artery disease is a disease which occurs due to the buildup of plaque in the coronary arteries. Coronary arteries are the main arteries that supply nutrients and oxygen rich blood to the heart muscles but when there is a buildup of plaque inside the coronary arteries, the clot is formed which completely or partially blocks the supply of blood to the heart muscles.
When the supply of oxygen rich blood is partially blocked, it is known as angina or chest pain.
When the supply of oxygen rich blood is completely blocked, it is known as a heart attack.
There are various risk factors of coronary heart disease such as high blood pressure, high blood cholesterol (bad or low density lipoprotein), diabetes, obesity, lack of physical activity, and cigarette smoking.
2. Diabetes mellitus
It is estimated that approximately 425 millions of people across the world are living with diabetes and this estimation is believed to rise in the coming years. Diabetes mellitus is a serious and chronic disorder which occurs when the sugar level in the blood becomes too high than normal. Diabetes is categorized into two types -
Type 1 indicates high sugar level in the blood due to lack of production of insulin.
Type 2 indicates high sugar level in the blood due to ineffective usage of produced insulin by the body. It is also known as insulin resistance.
Diabetes can occur due to one or both factors. Insulin is a hormone that is produced by the pancreas in the body and is responsible for regulating the sugar level. Impairment in the production or usage of insulin leads to the accumulation of sugar in the blood, resulting in diabetes mellitus.
Cancer is one of the most life threatening diseases which is responsible for millions of deaths. According to the World Health Organization (WHO), Cancer is a second leading cause of deaths globally and is responsible for an estimated 9.6 millions of deaths in 2018.
Cancer is a disorder which occurs when the cells inside the body grow abnormally and out of control. The bodies are made up of millions of cells and when these cells are damaged, they start to grow uncontrollably. The controlled cells lead to the formation of a lump which is known as a tumor. Cancer can occur in any part of the body, including the bones and the skin.
It is believed that almost one third of total cancer deaths are due to the five leading behavioral and dietary habits, namely high body mass index, lack of nutrition, tobacco use, alcohol consumption, and lack of physical activity.

It is a disease which occurs due to the builds up as tangles or twisted fibers in the center of the brain cells and plaques of protein material outside the brain cells. These plaques and tangles affect the messages inside the brain and cause damage to the connection between brain cells. As a result, the cells die and eventually, no information can be remembered.
