Can Mono Cause Liver Enzymes to Be High? The Mechanisms, Ranges, and Recovery Timeline
Yes, infectious mononucleosis can raise liver enzymes, and it does so in roughly 60 to 75 percent of people who develop the illness. The elevation is usually mild, peaking one to three weeks after symptoms begin.

Can Mold Affect Your Kidneys? The Immune Pathway, Timeline, and Risk Thresholds
Yes, mold can affect your kidneys, but almost never by growing inside them.

Can Modafinil Cause Anxiety? A Dose-by-Dose Nervous System Breakdown
Yes, modafinil can cause anxiety, and it does so in roughly 8 to 25 percent of users depending on dose and history. The mechanism is dose-dependent norepinephrine and dopamine accumulation, plus a weaker but real downstream cortisol rise.

Can Mice See in the Dark? The Rod-Cone Tradeoff, Real Limits, and Test Methods
Yes, mice can see in near-total darkness, but not by magic and not by any light-amplifying structure.

Can Mice Become Immune to Poison? The Real Genetics Behind Rodenticide Resistance
Yes, mice can become immune to poison, but not in the way most people imagine. They do not develop antibodies or white blood cells that neutralize toxins.

Can Mold Cause Brain Lesions? The Evidence, Mechanisms, and Limits
Yes, mold can cause brain lesions, but only through specific and relatively uncommon routes, and the evidence is strongest for invasive fungal infection in immunocompromised people rather than for common household mold exposure.

Can Menopause Cause Premature Ventricular Contractions (PVCs)? The Estrogen-Trigger Mechanism Explained
Menopause does not directly cause premature ventricular contractions (PVCs), but the hormonal transition can unmask or worsen them.

Can Metoprolol Cause Low Heart Rate? The Dose Threshold, Timeline, and Who Is at Risk
Yes, metoprolol can cause low heart rate, and it does so by design: the drug blocks beta-1 receptors in the heart's sinoatrial node, slowing the rate at which the heart's natural pacemaker fires.

Can Men Go Through Postpartum Depression? The Science, Timeline, and Hormonal Triggers
Yes. Men can experience postpartum depression, and the science is now clear enough that major clinical bodies treat it as a real, diagnosable condition rather than a sympathetic reaction to a partner's illness.

Can Menopause Cause Sciatica? The Hormone-Nerve Link Explained
Menopause does not cause sciatica directly, but the hormonal shift can raise your risk of it.

Can Measles Cause Blindness? The Eye Damage Timeline and Who Is Most at Risk
Yes, measles can cause blindness, and it does so through several distinct routes. The most common is measles keratitis, a direct viral infection of the cornea that affects roughly 50 percent of measles patients and usually heals.

Can Men Have Low Iron? Why Male Iron Deficiency Is Underdiagnosed
Yes, men can have low iron, and iron deficiency affects an estimated 2 to 5 percent of adult men in the United States, with iron deficiency anemia in roughly 1 to 2 percent.

Can Menopause Cause Bone Pain? The Hormone-Bone Mechanism Explained
Yes, menopause can cause bone pain, and the mechanism is largely estrogen withdrawal. Estrogen is a brake on osteoclasts, the cells that dissolve bone.

Can Men Lose 100 Pounds in 6 Months? A Realistic Timeline and What It Actually Costs the Body
Yes, a man can lose 100 pounds in 6 months, but only at the extreme edge of human physiology, and it requires a starting weight well above 300 pounds, medically supervised very-low-calorie eating, and resistance training to protect muscle.
