Thanks for your question on Healthcare Magic. I can understand your concern. Since she is having uncontrolled hypertension (systolic pressure of 190mmhg), we should first rule out pulmonary edema as cause for her wheezing. So get done ecg and 2d echo to rule out pulmonary edema. Another possibility is bronchitis. Since she is having diabetes, lung infection is common and this infection can cause bronchitis and wheezing. So get done chest x ray and PFT (pulmonary function test) for bronchitis. On the basis of above reports, she may need diuretic, antibiotic and inhaled bronchodilator. Strict control of blood pressure is must. Hope I have solved your query. I will be happy to help you further. Wishing good health to your mother. Thanks.
