Thanks for asking.
Based on your query, my opinion is as follows.
1. As you agree, your diet is poor, which is contributing to malnutrition
affecting your overall gut.
2. Need to improve diet, with protein rich and moderate fat and carbohydrate
diet. Being on blood thinners, should not affect much of your diet. The diet should be rich in soluble fiber from banana and other fruits and vegetables.
3. More fiber intake will lead to more output. Along with it, good hydration is essential. If nutrition improves, anemia
should improve. Get a complete hemogram along with peripheral smear. Based on reports, further nutritional advise can be thought of.
4. Continue blood thinners and other medications as advised. Diet improvement is foremost and you need to start from here.
Hope it helps.
Any further queries, happy to help again.
