<s>[INST] Feeling lightheadedness, also dizziness, body shaking, and dry nose blockage. Sometimes just cannot breathe, also last 2 and 1/2 months, lost 4.5 kg. Suffering diabetes, taking Ameryl 1 mg , suffering from hyper tension, taking Telma 20 , feeling that it is something to do with brain. Please help [/INST] Hello and welcome to ‘Ask A Doctor’ service.  I have reviewed your query and here is my advice. The symptoms mentioned can occur when BP is too high, or there may be very low sugar (hypoglycemia). Since there is no mention about any BP readings or blood glucose levels (fasting, PP and HbA1c%), it is really difficult to comment.Weight loss is seen in uncontrolled hyperglycemia as a lot of glucose is lost through urine. Ideally a person with controlled diabetes should have Fasting glucose closer to 100 mg, PP 150 to 160 mg & HbA1c%Then one feels absolutely healthy and all the long term complications of diabetes can be either postponed or prevented. Similarly BP should be 120 -130/ 70 to 80 mm Hg. when on proper treatment. Hope I have answered your query. Let me know if I can assist you further.Regards, Dr. Prabhakar Laxman Jathar </s>
