・I have a big belly.
・My stomach got big.
・My belly has grown a lot.

「我有小肚子了。」英語會說： I have a big belly. 、 My stomach got big. 或是 My belly has grown a lot. 等句型。
※「變胖了」可以用 I've gotten fat 或 I got fat 來說明。

When I was young, I was very skinny, but recently my belly has grown a lot.
（我年輕的時候很瘦，但最近肚子變大了。）
