Background: There has been an increase in the prevalence of hypertension globally and a trend towards poor control of hypertension. Despite the development of new guidelines on the management of hypertension, it remains a difficult disease to control. 

Methods: The study was an intervention (before and after) study of 386 patients aged 18 to 70 years with uncontrolled hypertension. A simple random sampling technique with the computer-generated random numbers was used for selection of respondents.

Results: Majority (58.3%) of the respondents who were overweight had Diastolic blood pressure of less than 100mmHg while a minority (41.7%) of the respondents who were overweight had diastolic blood pressure of 100 mmHg to 110mmHg. A minority (42.1%) of the respondents who were obese had diastolic blood pressure of less than 100mmHg while a majority (57.9%) of the respondents who were obese had diastolic blood pressure of 100 mmHg to 110mmHg.  However, the association was statistically significant (?2 = 9.845, p-value = 0.02). There was a significant difference between the mean first Systolic blood pressure and the mean third systolic blood pressure. (< 0.001, 95% CI 19.01- 23.04). Also, there was a significant difference between the mean first Diastolic Blood pressure and the mean third Diastolic Blood pressure (p < 0.001, 95% CI 11.13-11.56). 

Conclusion: Respondents with higher body mass indices had higher blood pressures. After health education and counselling of the patients, there was a significant difference between the mean first diastolic blood pressure at first visit and the mean third diastolic blood pressure after two months. Also, there was a significant difference between the mean first systolic blood pressure and the mean third systolic blood pressure. The results showed that there was a significant reduction in the blood pressures of the respondents after the intervention.
