Thank you for your contact to HCM. I understood your concern. I think his condition connects with lost of blood after surgery. He should follow iron riched diet:spinach,dates, raisin, pomegranate,apple, carrots,beet roots,buckwheat,peas and proteins(meat, curd, fish)for good absorption of iron.
You might require to check
blood test.For incresing BP he needs 4 meals in a day, chocolate, tea, coffee every day. Use alternating shower, do exercises, swimming.
For
anxiety he can take
ashwagandha 2 capsule daily for 1 month.
I advice you to take
revital for men 1 tablet daily for 1-2 month for increasing your tonus and energy.
Take care.
Best regards!
