can allergies cause hypertension

The relationship between allergies and hypertension is intricate. Typically, allergic reactions do not directly induce hypertension, but certain allergy symptoms and the medications used to treat them can influence blood pressure levels.

Initially, during an allergic response, the body releases chemicals such as histamine, which can lead to vasodilation and a consequent decrease in blood pressure. However, this reduction is usually short-lived and minor, not significant enough to result in sustained hypertension. Moreover, some allergy medications, including antihistamines and corticosteroids, while effective in relieving allergy symptoms, may exert some impact on blood pressure with chronic use. For instance, certain antihistamines might lead to side effects like dry mouth and constipation, whereas corticosteroids could cause fluid retention, indirectly affecting blood pressure. Furthermore, severe allergic reactions like anaphylactic shock are medical emergencies requiring prompt treatment. In such instances, blood pressure may plummet rather than increase.

Thus, while allergic reactions and allergy medications can have some effect on blood pressure, they generally do not directly cause hypertension. If you have hypertension or other health concerns, it is advisable to follow your physician's guidance, use medications prudently, and monitor your blood pressure regularly. Should you have any queries or experience discomfort, please consult a healthcare professional without delay.
