If you have secondary hypertension caused by a thyroid problem, getting your thyroid hormone levels back to normal will basically bring your blood pressure back to normal as well. Unsurprisingly, the systolic blood pressure was higher in hyperthyroid patients.
Hypertension, most commonly diastolic, is raised in patients with hypothyroidism because of raised peripheral vascular resistance. Hypertension is caused by hypothyroidism in 3% of patients with high blood pressure. Thyroid hormone supplements do not always lower the blood pressure. Blood pressure is highly influenced by thyroid disease. The effects of hyperthyroidism include increased cardiac output, contractility, tachycardia, widened pulse pressure, less systemic vascular resistance and increased basal metabolic rate. Low blood pressure is linked with adrenal fatigue. Symptoms of adrenal fatigue may consist of constant tiredness, hypoglycemia (low blood sugar) and low blood pressure. It’s not uncommon for people with Hashimoto’s hypothyroidism to also suffer from few forms of adrenal imbalance, including adrenal fatigue. Blood pressure can rise due to variety of reasons when the body is suffering from hypothyroidism. There are several examples of what the body does to correct itself when hypothyroidism occurs. If the kidneys no longer filter waste when a person’s blood pressure is low, a chemical called angiotensin is released, raising the blood pressure in the body. Also, if the body does not react to medication for a T4 deficiency, then the body will naturally raise the blood pressure to combat the issue. The human body will also cut blood to the hands and feet to concentrate on the body’s core. In turn this will raise the blood pressure by keeping blood in the smaller vessels of the body. It constricts the vessels in an effort to increase the blood levels when low blood pressure is apparent.
