Hello

Thanks for the query

I would like to answer your questions one by one

1. There is no permanent solution for Hiatus hernia, although surgical options are present but they do not cure the symptoms completely.
Antacids and laxatives reduce absorption of vitamins and minerals so you will need to take your supplements to prevent deficiency of them. It is quite possible that you have developed Vit b12 deficiency because of these medicines

2. Hypothyroidism will have to be treated with medications through out your life with medications

3. Your lifestyle modification should include. i. Cardio exercises like jogging, running, cycling. Avoid bending exercises and weight lifting
ii. Stop smoking and avoid alcohol
iii. Avoid spicy food
Iv. Do not sleep for at least two hours post dinner
V. Add lots of white meat, eggs and vegetables into your diet. This will help you with constipation and Vit b12 deficiency
Vi. Since you suffer from low blood pressure, adding salt to your diet can help

4. You can drink 250l of warm water mixed with honey and lime on an empty stomach in the morning. This will help your constipation and improve your appetite

5. Please avoid spicy, oily food, milk and milk products like cheese and butter

I wish you good health
