Obesity is a well-known cause of hypertension and is characterized by high aldosterone levels ( Goodfriend et al., 1998; Kurukulasuriya et al., 2011). One possibility is that adipocytes affect aldosterone production since they are active endocrine tissues ( Ronti et al., 2006). Indeed, Ehrhart-Bornstein et al. (2003) showed that isolated adipocyte secretory products could dramatically increase aldosterone production independent of ANG II in adrenocortical cells (NCI-H295R; Ehrhart-Bornstein et al., 2003). 2,13-epoxy-9-keto-10 (trans)-octadecenoic acid (EKODE) has also been shown to increase aldosterone production in a GC line. EKODE is produced by the oxidation of linoleic acid by hepatocytes. Incubation of adrenal cells with EKODE increased aldosterone production independently of ANG II. Interestingly, adult humans have a positive correlation with blood EKODE and aldosterone levels ( Goodfriend et al., 2004). However, EKODE is unlikely the molecule responsible for the effect seen by Ehrhart-Bornstein et al. (2003), as adipocyte secretory products were not oxidized by hepatocytes. A subsequent study showed that adipocyte-derived factors from SHR/cp rats (model of metabolic syndrome with hypertension) stimulate aldosterone production by increasing ADS expression and STAR activation despite ANG II receptor inhibition. Adipocyte-derived factors from normal rats failed to replicate these results ( Nagase et al., 2006). These effects might be mediated by leptin, which is a protein hormone secreted by adipocytes and is abnormally high in obese individuals ( Martinez-Rumayor et al., 2008; Huby et al., 2015). These in vitro studies have been validated and extended by in vivo investigations. For example, leptin infusion increased expression of ADS and serum aldosterone in a dose-dependent manner in mice with no effect on ANG II, K +, and corticosterone levels ( Belin de Chantemele et al., 2011; Huby et al., 2015). Huby et al. (2015) concluded that “leptin is a new regulatory factor of aldosterone secretion that acts directly in the adrenal cortex to promote ADS expression and aldosterone production” ( Huby et al., 2015). The leptin stimulatory effect on ADS and aldosterone was not abolished upon administration of ANG II or β adrenergic receptor inhibitors in mice, further supporting the notion of leptin as a novel effector of aldosterone production ( Huby et al., 2015). Leptin achieves these effects possibly through CaMK II, as leptin increased intracellular Ca 2+ concentration and elevated expression calmodulin and CaMK II ( Huby et al., 2015). Agreeably administration of leptin receptor antagonism abrogated leptin-mediated aldosterone secretion and lowered blood pressure in mice ( Huby et al., 2016). These studies carry crucial importance as hypertension in the obese population is a devastating health issue ( Kurukulasuriya et al., 2011).

Plasma renin and aldosterone follow a circadian rhythm because their levels fluctuated throughout the day, with their levels being highest in the mornings and lowest in the evenings in normal men ( Cugini et al., 1981; Thosar et al., 2019). Similar results have been found in PA and essentially hypertensive patients ( Kem et al., 1973; Lamarre-Cliche et al., 2005). Interestingly, plasma aldosterone circadian rhythm (PACR) may be under androgenic rather than renin control, as aldosterone acrophase precedes renin and is associated with cortisol ( Stern et al., 1986). Early studies in rats and human males found that dexamethasone treatment, a drug that suppresses ACTH, abolishes normal PACR, suggesting that it is under ACTH control ( Hilfenhaus, 1976; Takeda et al., 1984). Multiple regression analysis of aldosterone-stimulating factors at 3 hourly intervals confirmed PACR dependence on ACTH rather than renin or ANG II ( Takeda et al., 1984). The role of ACTH in PACR has also been implicated in PA ( Sonoyama et al., 2014). Klotho, Leptin, Natriuretic Peptides, and Circadian Rhythm

When these acupressure points for high BP are pressed, they release muscular tension and promote the circulation of blood to aid healing.
