The pathogenesis of essential hypertension is multifactorial and highly complex.
The disease involves the interaction of multiple organ systems and numerous mechanisms of independent or interdependent pathways.
Factors that play an important role in the pathogenesis of hypertension include genetics, activation of neurohormonal systems such as the sympathetic nervous system and renin-angiotensin-aldosterone system, obesity, and increased dietary salt intake.
Multiple factors are involved in short-term and long-term regulation of BP for adequate tissue perfusion; these include the following:
Cardiac output and circulatory blood volume
Vascular caliber, elasticity, and reactivity
Humoral mediators
Neural stimulation
The kidney is both the contributing and the target organ of the hypertensive processes, [1]

This for Secondary Hypertension
The role of corticosteroids in the pathogenesis of primary hypertension is not direct, as primary hypertension, also known as essential hypertension, is primarily associated with genetic and environmental factors. However, corticosteroids can indirectly contribute to increased blood pressure through various mechanisms:
Fluid Retention: Corticosteroids can lead to sodium and water retention in the body, increasing blood volume. This extra fluid can contribute to elevated blood pressure.
Increased Vascular Tone: Corticosteroids may enhance the sensitivity of blood vessels to vasoconstrictors, leading to increased vascular tone. This can contribute to higher blood pressure.
Potassium Loss: Corticosteroids can cause potassium loss, which may lead to an imbalance in electrolytes. Potassium is essential for maintaining proper blood vessel function, and its deficiency can contribute to hypertension.
Insulin Resistance: Prolonged corticosteroid use has been associated with insulin resistance, which can contribute to metabolic syndrome and hypertension.
It's important to note that while corticosteroids can contribute to secondary hypertension, which is hypertension caused by an underlying condition or medication, they are not a direct cause of primary hypertension. Primary hypertension is a multifactorial condition influenced by genetic, lifestyle, and environmental factors.
Individuals taking corticosteroids for medical reasons should be monitored closely by healthcare professionals, and measures may be taken to manage potential side effects, including blood pressure elevation. Adjustments to the corticosteroid dosage or the addition of antihypertensive medications may be considered if hypertension develops. Always consult with a healthcare provider for personalized guidance based on individual health conditions.
