營養不良都會導致脂肪肝？Why Does Not Eating Enough Cause Fatty Liver?
「藥劑師，點解我都無大魚大肉，日日都捱杯麵，都有脂肪肝嘅？有無搞錯！」
“Hello Pharmacist. I am always thin and don’t eat too much, but why do I get fatty liver? It doesn’t make sense!”
有人或許會奇怪，營養過剩會造成脂肪肝，那為什麼營養不良也會造成脂肪肝呢？其實很簡單，營養過剩屬於原材料太多，而營養不良屬於加工過程中的輔助材料不夠，同無法生產出合格的產品。當營養不良時，蛋白質缺乏，而導致極低密度脂蛋白合成減少，這樣造成肝轉運三酸甘油酯發生障礙，脂肪在肝內堆積，引起脂肪肝。常見的成因還有酗酒、肥胖、糖尿病和三酸甘油酯過高。
The common cause of fatty liver includes obesity, alcohol abuse, diabetes and high triglyceride levels. However, chronic malnutrition will also cause fatty liver. Why? Let’s think our liver as a factory and our food as the raw materials. When we have imbalanced diet, we could not get sufficient materials we need. As a result, our liver could only make products of low quality. Lack of essential nutrients, such as protein, disturbs the synthesis of very-low-density lipoprotein (VLDL) and interfere the triglyceride transportation. Extra fats start to build up in the liver, forming fatty liver.
脂肪肝通常沒有明顯的病癥，但少數會出現黃疸、作悶作嘔、腹痛及腹脹。醫生可能在身體檢查時才發現你的肝臟發大，脂肪物質在肝細胞積聚。目前並無針對性的藥物治療脂肪肝。治療方向主要以清除病因為首要考慮，如戒酒、減肥、控制血糖及控制飲食等。
As fatty liver usually has no signs and symptoms, it is hard to discover until your doctor finds it out during examination for other reasons. On rare occasions, people may have symptoms such as jaundice, nausea and vomiting, abdominal pain and excess gas in the abdomen. There is no medical treatment for fatty liver. The major goal is to eliminate the cause of fatty liver, such as alcohol avoidance, weight loss, blood glucose control, regular exercise and balanced diet.
