新北市三樹金鶯診所醫師蕭捷健引述研究指出,減去5%體重即可使肝臟脂肪減少40%,並同步改善胰島素敏感度、血壓及睡眠呼吸中止症狀況。減重5%可能開始減藥,減重10%則可能開始停藥。

〔健康頻道/綜合報導〕減重不必等到瘦很多,內臟脂肪、降血壓、睡眠呼吸中止可能跟著一起改變。新北市三樹金鶯診所體重管理主治醫師蕭捷健引述研究指出,減去5%體重,肝臟脂肪可減少40%,且肝臟、肌肉與脂肪組織的胰島素敏感度同步改善。另有觀察研究發現,減重約5%可能開始減藥、減重10%則可能開始停藥。
蕭捷健於臉書「減重醫師 蕭捷健」發文分享,華盛頓大學研究發現,只要減去 5% 的體重,肝臟裡面的油脂就能少掉 40%。他以其學員為案例提到,學員兩個多月從 91 公斤掉到 85 公斤,體脂 30% 降到 23%,內臟脂肪 10.5 降到 7.1,肌肉還增加1公斤,後來這位學員回診,其他診所的醫師應允他原本的血壓藥可以停了。
為什麼減重一點點,脂肪肝卻可改善這麼多?蕭捷健說明,《Cell Metabolism》一篇隨機對照試驗顯示:減 5% 體重後肝臟脂肪掉 40%,而且肝臟、肌肉、脂肪組織的胰島素敏感度是同時改善的,不用等你瘦到原本預期瘦下來的目標體重。
他接著說,只要熱量開始出現赤字、胰島素敏感度改善,肝臟就會很快把多餘的脂肪動員出去。所以常常是體重才剛開始下降,脂肪肝和代謝狀況就已先明顯改善。
減5%可能開始減藥
減重對血壓控制也可能帶來影響。蕭捷健表示,一份追蹤100名減重門診患者的觀察研究顯示,受試者平均減重12.2公斤,收縮壓及舒張壓分別下降9.1及6.3mmHg,各大類降血壓藥物都有人成功減量。
研究也將減重幅度與藥物調整進行觀察,減重5%可能開始減藥,減重10%則可能開始停藥。上述學員減重6.6%,也剛好達到減重後可能出現藥物調整的階段。
每減1公斤呼吸中止減少
減重對睡眠呼吸中止也可能帶來改善。蕭捷健提到,Sleep AHEAD研究中,減重組1年平均減少10.8公斤,每小時呼吸中止次數比對照組少9.7次,完全緩解的人數則是對照組的3倍。換算下來,每減 1 公斤,1小時就少窒息 0.7 次。「難怪不再做噩夢了」他這麼說著。

Ke Tingjie, an ophthalmologist at the National Taiwan University Branch in Hsinchu, pointed out that glaucoma often has no obvious symptoms in the early stages. Even if the intraocular pressure is normal, the optic nerve may be damaged. He reminded high-risk groups such as those with high myopia and family history to have regular eye examinations to avoid delayed treatment and severe visual field damage.

The article points out that the BMI index has limitations and cannot accurately reflect body composition, which may mislead bodybuilders and those with excess visceral fat. Introducing the BRI index (Body Roundness Index) as an alternative, which is calculated through height and waist circumference, and can better assess visceral fat accumulation and related health risks, especially for middle-aged and elderly men, which is more accurate in predicting chronic diseases. The article also provides the measurement method, reference range and limitations of BRI, emphasizing that healthy lifestyle is the core.

Pulmonary nodules are common in physical examination, and more than 95% are benign. However, the risk of malignancy depends not only on the size, but also on the density type (for example, mixed ground-glass nodules have a higher risk), morphological characteristics (burrs, lobes, etc. increase the risk) and dynamic follow-up changes. Non-smokers may also suffer from lung cancer, which is often asymptomatic in the early stages. People who develop dry cough, hemoptysis, shoulder and back pain, etc. need to be vigilant. Annual low-dose spiral CT screening is recommended for high-risk groups, and the report should be evaluated by a specialist.

Experts point out that consuming high-sugar, high-fat and highly processed foods for breakfast will accelerate biological aging. Studies have shown that the glycation end products in bacon, sugary drinks, and ultra-processed foods such as French croissants are all related to the risk of chronic diseases and accelerated aging. It is recommended to replace them with water or sugar-free drinks.

This article introduces the early identification methods of acute cerebral hemorrhage, on-site first aid principles in emergencies, and daily preventive measures. Cerebral hemorrhage has a sudden onset and a high rate of death and disability. It is crucial to understand the five typical symptoms such as "explosion-like pain" and master first aid knowledge such as dialing 120 and correct handling.

The Taipei Medical Doctors Association celebrated its 100th anniversary and held a thanksgiving tea party and new book launch event at the National Defense Medical University. Chairman Hong Deren and Deputy Minister of Health and Welfare Lin Jingyi attended the meeting and reviewed the century-old history of medicine, released a special book to showcase the spirit of doctors and looked forward to the future improvement of the medical environment.
