StarvationStarvation is a severe deficiency in caloric energy intake, below the level needed to maintain an organism's life. It is the most extreme form of malnutrition. In humans, prolonged starvation can cause permanent organ damage and eventually, death. The term inanition refers to the symptoms and effects of starvation. Starvation may also be used as a means of torture or execution. According to the World Health Organization (WHO), hunger is the single gravest threat to the world's public health.
Blood sugar levelThe blood sugar level, blood sugar concentration, blood glucose level, or glycemia, is the measure of glucose concentrated in the blood. The body tightly regulates blood glucose levels as a part of metabolic homeostasis. For a 70 kg (154 lb) human, approximately four grams of dissolved glucose (also called "blood glucose") is maintained in the blood plasma at all times.
Anorexia nervosaAnorexia nervosa (AN), often referred to simply as anorexia, is an eating disorder characterized by low weight, food restriction, , fear of gaining weight, and an overpowering desire to be thin. Individuals with anorexia nervosa have a fear of being overweight or being seen as such, although they are in fact underweight. The DSM-5 describes this perceptual symptom as "disturbance in the way in which one's body weight or shape is experienced". In research and clinical settings, this symptom is called "body image disturbance".
BuddhismBuddhism (ˈbʊdɪzəm , USalsoˈbuːd- ), also known as Buddha Dharma, and Dharmavinaya (), is an Indian religion or philosophical tradition based on teachings attributed to the Buddha. It originated in the eastern Gangetic plain as a śramaṇa–movement in the 5th century BCE, and gradually spread throughout much of Asia via the Silk Road. It is the world's fourth-largest religion, with over 520 million followers (Buddhists) who comprise seven percent of the global population.
Nonviolent resistanceNonviolent resistance, or nonviolent action, sometimes called civil resistance, is the practice of achieving goals such as social change through symbolic protests, civil disobedience, economic or political noncooperation, satyagraha, constructive program, or other methods, while refraining from violence and the threat of violence. This type of action highlights the desires of an individual or group that feels that something needs to change to improve the current condition of the resisting person or group.
Refeeding syndromeRefeeding syndrome is a metabolic disturbance that occurs as a result of reinstitution of nutrition in people and animals who are starved, severely malnourished, or metabolically stressed because of severe illness. When too much food or liquid nutrition supplement is eaten during the initial four to seven days following a malnutrition event, the production of glycogen, fat and protein in cells may cause low serum concentrations of potassium, magnesium and phosphate. Cardiac, pulmonary and neurological symptoms can be signs of refeeding syndrome.
Calorie restrictionCalorie restriction (caloric restriction or energy restriction) is a dietary regimen that reduces the energy intake from foods and beverages without incurring malnutrition. The possible effect of calorie restriction on body weight management, longevity, and aging-associated diseases has been an active area of research. Caloric intake control, and reduction for overweight individuals, is recommended by US dietary guidelines and science-based societies.
Tisha B'AvTisha B'Av (תִּשְׁעָה בְּאָב Tīšʿā Bəʾāv; tiʃʕa beˈʔav, the ninth of Av) is an annual fast day in Judaism, on which a number of disasters in Jewish history occurred, primarily the destruction of both Solomon's Temple by the Neo-Babylonian Empire and the Second Temple by the Roman Empire in Jerusalem. Tisha B'Av marks the end of the three weeks between dire straits and is regarded as the saddest day in the Jewish calendar, and it is thus believed to be a day which is destined for tragedy.
British RajThe British Raj (rɑːdʒ ; from Hindi , 'kingdom', 'realm', 'state', or 'empire') was the rule of the British Crown on the Indian subcontinent; it is also called Crown rule in India, or Direct rule in India, and lasted from 1858 to 1947. The Indian Rebellion of 1857 led to the British Crown assuming direct control of India from the East India Company in the form of the new British Raj through the Government of India Act 1858.
DyslipidemiaDyslipidemia is an abnormal amount of lipids (e.g. triglycerides, cholesterol and/or fat phospholipids) in the blood. Dyslipidemia is a risk factor for the development of atherosclerotic cardiovascular disease (ASCVD). ASCVD includes coronary artery disease, cerebrovascular disease, and peripheral artery disease. Although dyslipidemia is a risk factor for ASCVD, abnormal levels don't mean that lipid lowering agents need to be started. Other factors, such as comorbid conditions and lifestyle in addition to dyslipidemia, is considered in a cardiovascular risk assessment.
Electrolyte imbalanceElectrolyte imbalance, or water-electrolyte imbalance, is an abnormality in the concentration of electrolytes in the body. Electrolytes play a vital role in maintaining homeostasis in the body. They help to regulate heart and neurological function, fluid balance, oxygen delivery, acid–base balance and much more. Electrolyte imbalances can develop by consuming too little or too much electrolyte as well as excreting too little or too much electrolyte. Examples of electrolytes include: calcium, chloride, magnesium, phosphate, potassium, and sodium.
GluconeogenesisGluconeogenesis (GNG) is a metabolic pathway that results in the generation of glucose from certain non-carbohydrate carbon substrates. It is a ubiquitous process, present in plants, animals, fungi, bacteria, and other microorganisms. In vertebrates, gluconeogenesis occurs mainly in the liver and, to a lesser extent, in the cortex of the kidneys. It is one of two primary mechanisms – the other being degradation of glycogen (glycogenolysis) – used by humans and many other animals to maintain blood sugar levels, avoiding low levels (hypoglycemia).
LeptinLeptin (from Greek λεπτός leptos, "thin" or "light" or "small") is a protein hormone predominantly made by adipose cells and its primary role is likely to regulate long-term energy balance. As one of the major signals of energy status, leptin levels influence appetite, satiety, and motivated behaviors oriented towards the maintenance of energy reserves (e.g., feeding, foraging behaviors). The amount of circulating leptin correlates with the amount of energy reserves, mainly triglycerides stored in adipose tissue.
PheochromocytomaPheochromocytoma is a rare tumor of the adrenal medulla composed of chromaffin cells, also known as pheochromocytes. When a tumor composed of the same cells as a pheochromocytoma develops outside the adrenal gland, it is referred to as a paraganglioma. These neuroendocrine tumors typically release massive amounts of catecholamines, metanephrines, or methoxytyramine, which result in the most common symptoms, including hypertension (high blood pressure), tachycardia (fast heart rate), and diaphoresis (sweating).
Ta'anitA ta'anit or ta'anis (Mishnaic Hebrew: תענית) is a fast in Judaism in which one abstains from all food and drink, including water. A Jewish fast may have one or more purposes, including: Atonement for sins: Fasting is not considered the primary means of acquiring atonement; rather, sincere regret for and rectification of wrongdoing is key. Nevertheless, fasting is conducive to atonement, for it tends to precipitate contrition. Therefore, the Bible requires fasting on Yom Kippur.
Alcohol (drug)Alcohol, sometimes referred to by the chemical name ethanol, is a depressant drug that is the active ingredient in drinks such as beer, wine, and distilled spirits (hard liquor). It is one of the oldest and most commonly consumed recreational drugs, causing the characteristic effects of alcohol intoxication ("drunkenness"). Among other effects, alcohol produces happiness and euphoria, decreased anxiety, increased sociability, sedation, impairment of cognitive, memory, motor, and sensory function, and generalized depression of central nervous system (CNS) function.
