Thanks for posting your query.
All described symptoms may be due to hypothyroidism
and you should consult with endocrinologist
and should go for appropriate dose of synthyroid.
If all symptoms still persist then you should go for endoscopy
and blood sugar level.
These two hormonal disorders are commonly associated with abdominal heaviness and dyspeptic symptoms.
You should also consult with physician and gastro-physician.
You should also take proton pump
inhibitors and prokintic agent for better relief of your symptoms.
