Causes of Obesity

In the medical field, obesity is categorized into two types: primary (simple) obesity and secondary obesity. Primary obesity occurs without any other physical diseases and is solely due to irregular lifestyle, unscientific eating habits, and lack of exercise, leading to weight gain. This type can be managed with lifestyle adjustments and proper dietary guidance to reduce weight. Secondary obesity, which is less common, often involves endocrine disorders such as Cushing's syndrome. This condition can arise from issues with the pituitary or adrenal glands, or other parts of the body such as tumors, leading to excessive secretion of cortisol. This in turn causes redistribution of body fat, leading to characteristic signs like moon face, buffalo hump, and accumulation of subcutaneous fat which are manifestations of obesity. Additionally, conditions like hypothyroidism can lead to myxedema, contributing to obesity, as well as drug-induced obesity. Examples include patients with nephrotic syndrome or lupus who experience weight gain from prolonged use of corticosteroids. Therefore, the causes are diverse and require differential diagnosis by a specialist based on the individual's condition.

What medicine is taken for obesity?

Regarding obesity, first and foremost, one should not eat arbitrarily, meaning one should not randomly choose the so-called weight loss drugs available on the market. For obesity, we identify two types: primary obesity and secondary obesity. Primary obesity occurs without any specific reason, merely due to an irregular lifestyle, unhealthy diet, lack of exercise, etc., leading to weight gain. Secondary obesity has identifiable medical causes; for example, weight gain caused by taking large amounts of exogenous hormones; or hypothyroidism leading to myxedema, which causes weight gain; or issues with the pituitary or adrenal glands leading to excessive secretion of cortisol in the blood, causing a redistribution of fat that results in Cushing's syndrome, among others. For these types of secondary obesity, it is important to identify the underlying causes and treat them accordingly. For primary obesity, it is not advisable to recommend weight loss drugs commonly found on the market. The first recommendation is to control the diet scientifically, combined with a certain intensity of aerobic exercise to reduce weight. Caution is advised with those weight loss drugs sold by online marketers; one should not consume them carelessly.

Can people with hyperuricemia eat eggs?

In the case of hyperuricemia, we primarily recommend a low-purine diet to prevent the onset of gouty arthritis. As for the nutritional content of eggs, they are considered a food with a moderate level of purines. Therefore, when uric acid levels are relatively high, it is still possible to consume them in moderation. Aside from diet, it is also necessary to drink plenty of water or to alkalize the urine using baking soda tablets even if there is a transient increase in blood uric acid levels. If sufficient water is consumed, it is less likely for deposits to form in the joints. If deposits do not easily form, it also relatively reduces the possibility of triggering inflammatory responses, thus preventing the occurrence of gouty arthritis. Therefore, it is possible to consume an appropriate amount of eggs, but it is also important to drink plenty of water and appropriately alkalize the urine.

What department do you see for obesity?

The preferred specialty is endocrinology and metabolism because obesity itself is a metabolic disease. Besides the commonly known simple obesity, there is also a type called secondary obesity. The distinction between the two is that in simple obesity, the body does not suffer from any other disease; weight gain is merely caused by unscientific diet, irregular lifestyle, and lack of exercise, which can be resolved through some scientific methods. Another type is called secondary obesity, such as a common disease in endocrinology called Cushing's syndrome. It is caused by a tumor or hyperplasia in the pituitary or adrenal glands, or other reasons that lead to an excessive secretion of cortisol in the blood, consequently causing a redistribution of body fat, leading to moon face, buffalo hump, and accumulation of subcutaneous fat in the abdomen. Common in endocrinology, hypothyroidism can also lead to weight gain. This requires endocrinology specialists to diagnose and identify the specific condition in order to provide appropriate treatment.

What tests are needed for obesity?

Obesity is divided into simple obesity and secondary obesity. Simple obesity refers simply to being overweight without any other primary diseases. Secondary obesity requires examination of certain conditions, such as hypothyroidism, which can lead to obesity, thus necessitating thyroid function tests; or Cushing's syndrome, which involves increased body weight due to excessive corticosteroid hormones produced by various causes, necessitating an examination of the cortisol rhythm and sometimes a dexamethasone suppression test, magnetic resonance imaging (MRI) of the pituitary, and CT scan of the adrenal glands; also conditions such as depression or psychiatric illnesses that can lead to weight gain, requiring corresponding psychiatric scales, among others. In addition to these tests, it is also necessary to consider the patient's clinical symptoms and then conduct targeted examinations based on these symptoms.

Is leukopenia severe?

The normal value of white blood cells in the human body is 4 to 10×10^9/L. White blood cells mainly consist of neutrophils and lymphocytes, along with some other types of eosinophilic and basophilic granulocytes. If the total white blood cell count decreases, generally falling below 4 to 10×10^9/L, it is referred to as leukopenia. Among these, neutrophils are the most related to the body's immune response. If neutrophils decrease to less than 1.5×10^9/L, it is defined as neutropenia, which is very serious. If neutropenia occurs, the resistance to infections is greatly lowered, making the body highly susceptible to various infections. Active treatment to increase white blood cells is necessary; otherwise, any infection may lead to severe conditions like septicemia and septic shock, which can even be life-threatening.

What are the dietary restrictions for obesity?

If it's obesity, it means a body mass index (BMI) greater than 28. In terms of dietary restrictions for obesity, the general principles are low salt and low fat. First and foremost, intake of fats should be limited, including both the cooking oils and foods consumed. Preference should be given to vegetable oils, and consumption of animal fats should be minimized. Even with vegetable oils, there is a limit to how much should be used, as excessive amounts can also exceed health standards. Furthermore, one should eat less fast food and junk food, such as various fried foods or those containing excessive seasonings, and these foods should be consumed minimally. There are also "invisible" fats to consider, such as those found in nut snacks and various small packaged snacks like peanuts and fried beans, which are very high in calories and should be consumed less. Additionally, sugary drinks like iced tea and pear syrup drinks should be avoided. The overall principle is a low-calorie diet, avoiding high-calorie foods.

Which department does obesity belong to?

Obesity is defined by calculating the Body Mass Index (BMI), where one's weight in kilograms is divided by their height in meters squared to obtain a numeric value. If the BMI is 28 or higher, it is defined as obesity. There are two types of obesity based on BMI excess: simple obesity and secondary obesity. Simple obesity occurs without any other internal medical conditions, purely due to weight gain. Secondary obesity may be due to other psychosomatic diseases that lead to an increase in BMI. Therefore, it is recommended to consult the endocrinology department for physical examinations and laboratory tests to determine whether the obesity is simple or secondary. Hence, a consultation in the endocrinology department is advised.
