Background – High blood pressure or hypertension is a condition where the blood pressure is higher than 140/90 mmHg. The mechanisms of hypertension as known are changes in anatomy and physiology of the vessels, increasing of RAAS (Renin Angiotensin Aldosterone System) mechanism, and increasing of sympathetic nervous system. Each mechanisms as mentioned has its own paths, but all of them is somehow connected and at the end together it would cause systemic vasoconstriction and would be followed by systemic hypoxia therefore it probably caused headache sensation. The headache’s characteristic could be vary and different to each person, but based on headache’s pathophysiology it is known that hypertension has the closest connection to Tension-Type Headache (TTH). Purpose – Find out is there any connection between hypertension and the frequency of TTH. Methods – This research uses the observational or analytic survey research with cross sectional approach. Sample is determined by purposive sampling technique. The diagnose of TTH is made based on International Classification of Headache Disorders the 3rd edition, year 2013. Results – The number of samples in this research contains 55 subjects who has hypertension with 29 of them are diagnosed by TTH and 26 of them are not diagnosed by TTH. The significance value is p = 0,364 (p > 0,05) for both variables that means there is no correlation between the two variables. Conclusions – Hypertension does not has a correlation with the frequency of tension-type headache.
