您總是感到飢餓嗎?可能是這些原因

It's normal to feel hungry after not eating for a few hours, but persistent hunger after eating may indicate a medical problem.

There is a problem with your health

Frequent hunger may indicate an underlying health problem such as diabetes, hyperthyroidism, hypoglycemia, premenstrual syndrome, or a mental health issue such as depression. Please consult your doctor for diagnosis and treatment.

diabetes

Diabetes prevents glucose from reaching cells, causing increased urination and food cravings. Despite increased food consumption,

People with type 1 diabetes may still lose weight. Symptoms include excessive thirst, frequent urination, unexplained weight loss, blurred vision, slow wound healing, and tingling or pain in the extremities. Fatigue may also be present.

Hypoglycemia

Hypoglycemia, or hypoglycemia, occurs when blood sugar levels drop. This is common in diabetes, but can also be caused by other health problems, such as hepatitis, kidney disease, insulinoma, or problems with the adrenal gland or pituitary gland. Severe cases may have symptoms such as slurred speech, difficulty walking, anxiety, palpitations, pale skin, tremors, sweating, and tingling around the mouth.

you are taking certain medications

Certain medications, such as antipsychotics, antidepressants, some diabetes medications , corticosteroids, anti-seizure medications, and certain birth control pills, may have the side effect of increasing your appetite. If you think your medication is causing excessive hunger, talk to a health care professional as there may be other options.

There are some drugs that make you want to eat. They are called appetite stimulants:

  • megestrol
  • Dronabinol
  • Oxandrolone
  • Mirtazapine
  • prednisone
  • Cyproheptadine
  • Valproic acid
  • Olanzapine
  • marijuana

you are too stressed

Excessive and chronic stress , anxiety, or tension can increase levels of a hormone called cortisol, which increases appetite and thus promotes hunger and food cravings. Many people under stress also crave foods high in sugar, fat, or both. It could be your body trying to "turn off" the part of your brain that's causing you worry.

you ate too fast

Several research reviews suggest that eating more slowly and chewing more per mouthful may increase feelings of fullness and reduce appetite. However, some studies have found no association between eating speed and satiety. Chewing slowly increases awareness of eating, giving the body and brain more time to release anti-hunger hormones and signal satiety. These tips are part of mindful eating. Other tips for reducing hunger include taking deep breaths before meals, pausing between bites, and chewing more.

You eat too many refined carbohydrates

Refined carbohydrates are highly processed foods that lack fiber, vitamins and minerals. They are quickly digested and converted into glucose, causing an increase in blood sugar and insulin levels. Insulin removes sugar from the blood, causing blood sugar levels to drop suddenly and signaling the need for more food.

To reduce your intake of refined carbohydrates, choose nutrient-dense, whole foods such as vegetables, fruits, legumes, and whole grains, which are high in fiber and help control hunger.

lack of sleep

Not getting enough rest affects the hormones in the body that control hunger, lowering leptin levels and increasing ghrelin levels, which affects appetite. You're also more likely to crave high-fat, high-calorie foods when you're tired. It is recommended for adults to sleep at least 7 hours a night.

Distracted while eating

Distractions while eating, such as while traveling, using electronics, or talking, are associated with increased appetite, calorie intake, and weight gain. Research suggests that impaired sensory awareness is one reason, as multitasking affects the amount of energy the brain allocates to each task, making it more difficult to recognize satiety signals. It can also affect the sense of taste and lead to more frequent, larger meals.

Too many calories in liquid

Liquid foods, such as meal replacement shakes, are more likely to make you feel full than solid foods because they are digested more quickly. This may lead to a tendency toward increased hunger. Likewise, sugary drinks may not satisfy hunger and may prompt people to snack more frequently. Research shows that liquid foods are less effective at suppressing hunger hormones than solid foods. Additionally, the less time required to consume liquids may lead to overeating because the brain is unable to receive satiety signals. Incorporating more solid, whole foods into your diet may help prevent persistent hunger.

you drink too much

Alcohol can stimulate appetite by affecting the judgment, desire and reward centers of the brain. A recent study showed that alcohol increases food cravings and overall food consumption. Even small amounts of alcohol can lead to the intake of more food because it does not provide a feeling of fullness. Drinking alcohol before or after a meal is associated with higher calorie intake. To minimize the impact on hunger, moderation or abstinence from alcohol is recommended.

you don't drink enough water

Drinking enough water has many health benefits for the brain, heart, skin and digestive system. Research shows that drinking water before meals can reduce caloric intake. One study found that participants who drank 2 glasses of water consumed nearly 600 calories. Dehydration can be mistaken for hunger, so drinking water between meals may help suppress your appetite. Health experts recommend adults drink 6-8 glasses of water a day, and eating water-rich foods can also help replenish your body.

Your diet is low in fat

Fat takes longer to digest and stays in the stomach longer. It also triggers the release of hormones that create a feeling of satiety. High-fat foods, such as coconut oil, fatty fish, walnuts, and avocados, can help you feel fuller longer.

Your diet lacks protein

Weak hair and nails are often the first sign of protein deficiency. Feel weak or hungry as protein provides energy and satisfies appetite.

Your diet lacks fiber

Fiber helps regulate gastric emptying and increases satiety, keeping you fuller longer. High fiber intake affects the release of appetite-reducing hormones and the production of short-chain fatty acids. Soluble fiber absorbs water and turns into a gel-like substance, making you feel fuller more easily than insoluble fiber.

you exercise a lot

Frequent exercise leads to high calorie burning. Resistance exercise can increase your basal metabolic rate (BMR), which is the number of calories your body burns during basic functions. Research shows that intense exercise can increase your metabolic rate the next day , which may lead to increased hunger. Long-term exercise can also increase appetite due to effects on hormonal and energy-regulating systems. However, research on the effect of exercise on basal metabolic rate is inconsistent, with one study involving overweight or obese adolescents finding no effect of exercise on basal metabolic rate. To prevent excessive hunger, athletes who exercise vigorously or for long periods of time can eat foods high in fiber, protein, and healthy fats. Moderately active individuals may not need to increase their caloric intake.

成年後懷疑自己有注意力不足過動症(ADHD),應該接受診斷嗎?

在過去,注意力不足過動症(Attention-Deficit/Hyperactivity Disorder, ADHD)多被視為「小孩的病」,很多成年人小時候從未被評估或診斷。直到近年社會對心理健康重視度提升,許多成人才開始懷疑,自己長期以來的專注困難、健忘、衝動或時間管理不良,可能與 ADHD 有關。這種「晚發現」的情況相當普遍,也引發了問題:成年後是否值得接受 ADHD 診斷?

在現代執法中,警察常使用所謂「非致命性武器」(less-lethal weapons),其中最廣為人知的便是 電擊槍(Taser)。電擊槍的設計初衷是提供一種介於徒手制服與槍械之間的選擇,藉由暫時性電擊使嫌疑人失去行動能力,以降低致命暴力發生的風險。然而,電擊槍並非完全無害,背後涉及的電流機制與人體生理反應值得深入探討。
