意外减肥的原因

A common cause of unplanned weight loss is an overactive thyroid gland, where your thyroid increases production of hormones that increase your metabolism. 焦虑, 失眠, 心慌, 颤抖, and heat sensitivity are additional symptoms of hyperthyroidism. These symptoms are telling of an overactive thyroid, especially if you also have a swelling in your neck, 哪一个可能是甲状腺肿. However, a blood test to check thyroid hormone levels is necessary to confirm hyperthyroidism.

严重的感染, 例如, 结核病和艾滋病毒, 以及炎症状况, 比如风湿性关节炎, also raise your metabolic rate and induce weight loss. Your doctor can assess your symptoms and check your blood for markers of infection and inflammation to rule out infective or inflammatory causes of weight loss.

Cancer is another condition that increases your body’s energy requirements and results in weight loss if your increased requirements aren’t met.

Additionally, digestive health problems can lead to unintentional weight loss. 例如, 克罗恩病, 恶心和腹泻会降低你的食欲, 当你的身体努力吸收营养时, making it difficult to meet your nutritional requirements. Celiac disease is another digestive disorder with weight loss as a symptom, as damage to your intestinal lining by gluten hinders nutrient uptake. 如果你有消化系统相关症状, your doctor may order tests for Crohn’s disease and celiac disease.

Undiagnosed diabetes is a further cause of unexplained weight loss. 当你的身体产生的胰岛素不足时, 你不能使用葡萄糖作为燃料, so you use your muscle and 脂肪 stores for energy. Sudden weight loss is more common in Type 1 Diabetes, though weight loss as a symptom is also seen in Type 2 Diabetes.

心理健康和减肥

Unintentional weight loss can also be a symptom of dementia. Significant weight loss in dementia may stem from reduced dietary intake as a consequence of difficulties feeding, 咀嚼, 和吞咽, as well as increased energy expenditure from wandersome behavior. 除了记忆力减退, further symptoms of dementia include difficulty with planning, 语言, 和浓度, 还有混乱, 幻觉, 改变心情, 以及性格的改变.

Alternatively, malnutrition may occur if you are dependent on alcohol or drugs. Weight loss is associated with alcohol dependence, 就像酗酒的时候, alcohol may replace food while interfering with nutrient absorption and increasing metabolic rate through inflammation. 与此同时, 对兴奋剂依赖, 比如可卡因和冰毒, 可以抑制你的食欲, while addiction to any drug can reduce your interest in eating once drug-seeking becomes your main focus.

Although unexplained weight loss doesn’t necessarily have a sinister cause, you should always see your doctor to investigate sudden weight loss that you can’t account for. 如果你因为健康问题而减肥, seeking early medical help allows timely diagnosis and treatment, giving you the best chance of managing your symptoms and minimizing complications.
