请教各位，身体变得消瘦，是不是只出现于1型糖尿病患者？2型糖尿病患者是不是不会变得消瘦？

换句话说，胰岛素抵抗（2型糖尿病）只会导致人体发胖？

进一步，如果能排除1型糖尿病，假如一个人不胖，或是比较消瘦，就不会有胰岛素抵抗，或说这个人饮食比较健康？

上面这些对吗？

 

网上查到：

Can type 2 diabetes cause weight gain?

Insulin resistance, which is a hallmark of type 2 diabetes, may also lead to weight gain. When the pancreas produces more insulin in response to insulin resistance, the hormone signals the muscles and liver to store blood sugar. After the muscles and liver are full, the liver sends excess blood sugar to fat cells for storage. This can also lead to weight gain.

Can type 2 diabetes cause weight loss?

As a consequence of insulin resistance, the pancreas produces more insulin to overcome the resistance. Eventually, the pancreas is unable to make enough insulin to get a sufficient amount of sugar into the cells. This causes blood sugar levels to rise.  Since the cells cannot get the energy they need from glucose, the body breaks down fat to use for energy instead. This can result in weight loss.

 

似乎是怎么说都可以。似乎能解释那些先胖后瘦，但一直瘦的呢？怎么解释？
