Nasal congestion is commonly caused by allergic rhinitis, or hay fever. This occurs when pollen, dust, mold spores, or other allergens are inhaled and irritate the nasal passage. Other causes of nasal congestion include the common cold or flu, a deviated septum, sinusitis or sinus infections, reaction to certain medications. Additionally, nasal congestion occurs in many women during pregnancy. In many individuals, nasal congestion is caused by food allergies. Those who are lactose intolerant often find themselves suffering from a stuffy nose. Your doctor can conduct allergy tests to identify your specific type of food allergy and recommend a new diet. Reducing the amount of dairy in your diet in addition to carbohydrates and sugar can improve the quality of your diet and reduce nasal congestion.
Shelton and Rajfer (2012) noted that androgen deficiency in aging men is common, and the potential sequelae are numerous. In addition to low libido, erectile dysfunction, decreased bone density, depressed mood, and decline in cognition, studies suggest strong correlations between low testosterone, obesity, and the metabolic syndrome. Because causation and its directionality remain uncertain, the functional and cardiovascular risks associated with androgen deficiency have led to intense investigation of testosterone replacement therapy in older men. Although promising, evidence for definitive benefit or detriment is not conclusive, and treatment of LOH is complicated.
