A disease is a particular abnormal condition that adversely affects the structure or function of all or part of an organism and is not immediately due to any external injury. Diseases are often known to be medical conditions that are associated with specific signs and symptoms. A disease may be caused by external factors such as pathogens or by internal dysfunctions. For example, internal dysfunctions of the immune system can produce a variety of different diseases, including various forms of immunodeficiency, hypersensitivity, allergies, and autoimmune disorders.
Stress, whether physiological, biological or psychological, is an organism's response to a stressor such as an environmental condition. When stressed by stimuli that alter an organism's environment, multiple systems respond across the body. In humans and most mammals, the autonomic nervous system and hypothalamic-pituitary-adrenal (HPA) axis are the two major systems that respond to stress. Two well-known hormones that humans produce during stressful situations are adrenaline and cortisol.
In medicine, comorbidity refers to the simultaneous presence of two or more medical conditions in a patient; often co-occurring with a primary condition. It originates from the Latin term morbus prefixed with co- ("together") and suffixed with -ity. Comorbidity includes all additional ailments a patient may experience alongside their primary diagnosis, which can be either physiological or psychological in nature. In the context of mental health, comorbidity frequently refers to the concurrent existence of mental disorders, for example, the co-occurrence of depressive and anxiety disorders. The concept of multimorbidity is related to comorbidity but is different in its definition and approach, focusing on the presence of multiple diseases or conditions in a patient without the need to specify one as primary.
Kidney failure, also known as renal failure or end-stage renal disease (ESRD), is a medical condition in which the kidneys can no longer adequately filter waste products from the blood, functioning at less than 15% of normal levels. Kidney failure is classified as either acute kidney failure, which develops rapidly and may resolve; and chronic kidney failure, which develops slowly and can often be irreversible. Symptoms may include leg swelling, feeling tired, vomiting, loss of appetite, and confusion. Complications of acute and chronic failure include uremia, hyperkalemia, and volume overload. Complications of chronic failure also include heart disease, high blood pressure, and anaemia.
Farmer's lung is a hypersensitivity pneumonitis induced by the inhalation of biologic dusts coming from hay dust or mold spores or any other agricultural products. It results in a type III hypersensitivity inflammatory response and can progress to become a chronic condition which is considered potentially dangerous.
A chronic condition is a health condition or disease that is persistent or otherwise long-lasting in its effects or a disease that comes with time. The term chronic is often applied when the course of the disease lasts for more than three months. Common chronic diseases include diabetes, functional gastrointestinal disorder, eczema, arthritis, asthma, chronic obstructive pulmonary disease, autoimmune diseases, genetic disorders and some viral diseases such as hepatitis C and acquired immunodeficiency syndrome. An illness which is lifelong because it ends in death is a terminal illness. It is possible and not unexpected for an illness to change in definition from terminal to chronic. Diabetes and HIV for example were once terminal yet are now considered chronic due to the availability of insulin for diabetics and daily drug treatment for individuals with HIV which allow these individuals to live while managing symptoms.
Self-care has been defined as the process of establishing behaviors to ensure holistic well-being of oneself, to promote health, and actively manage illness when it occurs. Individuals engage in some form of self-care daily with food choices, exercise, sleep, and hygiene. Self-care is not only a solo activity, as the community—a group that supports the person performing self-care—overall plays a role in access to, implementation of, and success of self-care activities.
Chronic care refers to medical care which addresses pre-existing or long-term illness, as opposed to acute care which is concerned with short term or severe illness of brief duration. Chronic medical conditions include asthma, diabetes, emphysema, chronic bronchitis, congestive heart disease, cirrhosis of the liver, hypertension and depression. Without effective treatment chronic conditions may lead to disability.
Chronic care management encompasses the oversight and education activities conducted by health care provider to help patients with long term illness and health conditions such as diabetes, hypertension, lupus, multiple sclerosis, and stopping of breathing during asleep learn to understand their condition and live successfully with it. This term is equivalent to disease management for long term conditions. The work involves motivating patients to persist in necessary therapies and interventions and helping them to achieve an satisfyingly and well-begin life.
The World Health Organization defines health as "a state of complete physical, mental and social well-being". Average life expectancy at birth was 78.7 in 2017. Heart diseases are responsible for the greatest number of deaths in the United States.

Hand eczema presents on the palms and soles, and may sometimes be difficult or impossible to differentiate from atopic dermatitis, allergic contact dermatitis, and psoriasis, which also commonly involve the hands. Even a biopsy of all these conditions may not result in a definitive diagnosis, as all three conditions may demonstrate spongiosis and crusting on the hands.
Gulf War syndrome (GWS) also known as Gulf War Illness or Chronic Multi-symptom Illness, is a chronic and multi-symptomatic disorder affecting military veterans of both sides of the Gulf War (1990–1991). A wide range of acute and chronic symptoms have been linked to it, including fatigue, muscle pain, cognitive problems, insomnia, rashes and diarrhea. Approximately 250,000 of the 697,000 U.S. veterans who served in the Gulf War have enduring chronic multi-symptom illness. From 1995 to 2005, the health of combat veterans worsened in comparison with nondeployed veterans, with the onset of more new chronic diseases, functional impairment, repeated clinic visits and hospitalizations, myalgic encephalomyelitis/chronic fatigue syndrome-like illness, post-traumatic stress disorder, and greater persistence of adverse health incidents.
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a disabling chronic illness. People with ME/CFS experience profound fatigue that does not go away with rest, as well as sleep issues and problems with memory or concentration. The hallmark symptom is post-exertional malaise, a worsening of the illness which can start immediately or hours to days after even minor physical or mental activity. This "crash" can last from hours or days to several months. Further common symptoms include dizziness or faintness when upright and pain.
Spoon theory is a metaphor describing the amount of physical or mental energy that a person has available for daily activities and tasks, and how it can become limited. The term was coined in a 2003 essay by American writer Christine Miserandino. In the essay, Miserandino describes her experience with chronic illness, using a handful of spoons as a metaphor for units of energy available to perform everyday actions. The metaphor has since been used to describe a wide range of disabilities, mental health issues, forms of marginalization, and other factors that might place unseen burdens on individuals.
