I think digestion problems are widely found in many of the people so what should be the tips to get rid off from that
A gluten free diet is a healthy start for many. Even going Paleo if that works for your body type.
Digestive enzymes help many people. Tums or such.
Including regular exercise into your lifestyle helps with digestion and increases metabolism.
Getting enough Fish Oil and Vitamin D daily, most people don't take enough. For fish oil 1 - 2,000 is enough and Vit D anywhere from 3 - 5,000 helps.
Eating a diet high in fibre.
