**11. Key comorbidities of hypertension comparable to COVID-19**

Many research studies have shown that the death rate in COVID 19 was more in patients aged above 50–60 years with hypertension [31].

Obesity with hypertension is also the determinant factor in increasing the seriousness of the disease, which deteriorates the patient's outcome by affecting the expansion of the diaphragm, decreasing the expiratory reserve volume, compromising the ventilation. Obesity increases the release of increased cytokines, causes atherosclerosis, and leads to cardiac problems, which reduces the recovery of the patients with COVID - 19 [31].
