Dabur Hingoli is an Ayurvedic digestive aid that may provide temporary relief from indigestion, gas, bloating, and mild constipation, as well as reduce heaviness after meals, but it is not a treatment for these conditions and does not address the root cause; given that you are experiencing constipation, heaviness after meals, and insomnia together, it is strongly recommended to consult a qualified physician who can conduct appropriate tests to identify the underlying causes and prescribe suitable medical treatment, while also guiding you on essential dietary and lifestyle modifications for lasting relief.
