Please post here your chosen topic and information about why you chose it. Note: it must be a NON-INFECTIOUS agent (with few exceptions and it cannot be what you chose for discussion 2), so it cannot be caused by an organism. Please review the syllabus for more details.
A reminder from the syllabus:

The disease or disorder should not be a common disease that has already addressed in our course. With rare exception, it should not be an infectious disease (caused by an infectious organism).
Common diseases should be AVOIDED, including coronary artery disease, Alzheimer’s disease, arthritis, diabetes, AIDS, hypo- and hyper-thyroidism, hypertension, psoriasis, sleep apnea, Lyme’s Disease, sinusitis, allergic rhinitis, mononucleosis, asthma, urinary tract infections, many STDs (check with your instructor), irritable bowel disease, strep throat, MRSA, polio, tuberculosis, Lockjaw, anorexia nervosa, autism, Down syndrome, and many cancers (check with your instructor).

The information you present should include sufficient detail to demonstrate that you have completed some preliminary research and should present a clear rationale for your choice.
If you’re struggling with ideas, think of something you or someone you know may be dealing with. Or perhaps take a look at webMD and see if you find something interesting. Or watch a medical show, like The Good Doctor.
Please change your Title of your discussion post to the name of the disease.
