What Are Charaka and Sushruta's Teachings About Digestive Issues - #2418

Been struggling with some major digestive problems lately—constipation one day, diarrhea the next. It’s like my stomach can’t figure out what it wants to do. My diet is pretty average, though I admit I eat a lot of processed food and drink a ton of coffee. Recently, I’ve started noticing this weird heaviness in my gut, especially after meals, and I feel tired no matter how much I sleep. I’ve heard about Ayurveda being good for digestion, so I started reading up on it, and the names Charaka and Sushruta kept coming up. Apparently, they’re like the OGs of Ayurveda? But I couldn’t figure out what exactly they said about digestion. I think one of them wrote something about "Agni," which is related to metabolism or something? Is it connected to what I’m feeling right now? Does it mean my Agni is weak or messed up? Also, I’ve been getting really bad skin breakouts, and someone told me that digestion and skin are linked according to Charaka’s teachings. But how? Are there specific remedies or foods they recommend to fix these problems? And what about herbs—are there any safe ones I can try without having to go all-in on Ayurveda right away? I just wanna know if following what Charaka or Sushruta said could actually help me or if I’m wasting my time trying to figure it out. Should I see an Ayurvedic doctor for my stomach issues? Are there modern equivalents of their methods in Western medicine? Any advice would be super helpful!
