Gas pain, bloating, stomach pain after eating about an hour later followed by nausea. what could this be? ive been having some constipation. but i have went the last 2 days this started last night what should i do? is this something to worry about?

You could try and relieve the constipation first but what you actually need more is a lifetime habit of eating food that would not hurt your gut. You may have had food high in gas production and the constipation cause blockage is why you have symptoms. You could exercise, and I know 'push ups' help the most, to unblock however increase water and fiber in your nutrition and consider nutritionist
