Since the last 20 years, i've issues of bloating after a heavy or spicy meal which goes away after a good sleep at night. my liver is always normal in the ultrasound and so are the lfts. does it indicate my liver is normal but weak to digest food?

If your liver ultrasound and liver function tests are all normal, then your liver is likely normal. The bloating after eating a spicy meal could be coming from your stomach or intestines. A GI doctor would be able to evaluate these symptoms and pursue further testing to determine the cause and provide proper treatment. Best of luck to you!

You may need to adjust your diet. Visit this site for foods that may help with your bloating: https://www.hopkinsmedicine.org/health/wellness-and-prevention/fodmap-diet-what-you-need-to-know Wish you good health!
