Speak with your doc: Given diabetes and asthma, there may be many reasons for your tiredness and your doctor can help sort that out. To name a few: it could be sleep apnea, vitamin deficiency, untreated allergic rhinitis/sinusitis, cardiac reasons, uncontrolled asthma, uncontrolled diabetes. The list is long and you should seek a physician evaluation.

DM11 BRONCHIAL ASTHM: Make sure your diabetes is well controlled and your bronchial asthma. If both conditions are ok check your vit. D and vit b complex supplements. There are other causes of fatigue also.
