Kindly discuss for your concern

Considering his age, percentage of Hb and other elements you should consult physician immediately and in person. He requires parental treatment..

Need for blood transfusion can be delayed for time being. First need to know about the morphological type of anaemia. He must undergo CBC with PBF and iron profile followed by Bone Marrow examination( if need be) to rule out any haematological malignancy as RBC count is too low. Also need to go for colonoscopy to look for any GI malignancy as patient is anyway due for Colon screening at age of 70 yrs. As patient is Diabetic , these symptoms could be explained by peripheral/ autonomic neuropathy. Need to recheck his Thyroid profile to look if his dosage of thyroxine is adequate . Would be worthwhile to know about the d blood glucose levels fasting & PP. In d meantime for symptomatic relief patient can take Tab. Betahistine 8 mg TID for dizziness Tab. Pregastar M HS Tab. Supradyn OD continue other medications he already is on NEEDS FEW MORE VISITS

Kindly consult

Low Hemoglobin needs extensive evaluation along with blood transfusion as of now.

At this age  with comorbidities and symptoms blood transfusion is advised oral supplements will take time and at this age he is also more prone to have cardiac complications so why to take risk but before that get iron profile and smear for type of anemia because some times at this age the anemia is dimorphic type so it will be easy for the treating physician to decide the further management. Get live function and kidney function test also done. Please take him to a general physician in your place for better evaluation and treatment. Thankyou so much for the detailed case history. Don't worry everything will be fine soon.

Kindly consult me for better evaluation

Need further evaluation

Blood transfusion is required if hb is below 7 or if he is having features of cardiac failure like breathlessness on exertion or leg swelling.  So, he doesn't require blood transfusion. Iron deficiency is one of the common cause for anemia, but not the only cause. So I wouldbsuggest you to confirm iron deficiency by getting serum iron, tibc, ferritin and peripheral smear to confirm the iron deficiency. His iron requirement has to be calculated, for which body weight is required. Based on that, duration can be calculated. Also we need to evaluate for the cause of iron deficiency if proven. You consult me for detailed discussion. Right now, continue the ongoing supplementation and get the above mentioned evaluation done. P.s I really appreciate the details of information given. Normally partial details are given. Good work there
