If I get mono, how long will my spleen stay swollen?

Duration of illness: The fact that one's spleen swells during the course of mononucleosis means that the spleen is functioning properly. It is a filter for bacteria and abnormal blood cells, and as such will swell in a state that gives rise to these conditions. The spleen size is often monitored by your doctor while you are ill and the recession of spleen size is an indication of improving health. ...Read more

Can smoking cigarettes effect your spleen if it is enlarged from mono? Can it effect your liver while recovering from mono.

Can smoking cigarettes effect your spleen if it is enlarged from mono? Can it effect your liver while recovering from mono.

Probably not: I am not aware of tobacco's effects on the spleen or liver, but it can cause throat, lung, and bladder plus some other forms of cancers. It also worsens asthma and causes emphysema especially for women. You should take this opportunity to quit smoking instead of asking for justification to smoke. Name me one health benefit from smoking and then we can talk. ...Read more

My 17 y-o softball player daughter has mono. Know about spleen risk. Clarify fully recovered/when she can return. 2 weeks in and fatigue only symptom.

May be fine now: You can always have her pcp evaluate her for an enlarged spleen (physical exam) and at this point if it never enlarged or is returning to normal size there would be minimal risk. Be aware that playing through fatigue places her at some increased risk of injury do to decline in vigilance. Some caution is reasonable until she is feeling up to her normal level. ...Read more

Not exactly...: Your son should have had a mono spot test, heterophile antibody test, of formal ebv titers ($$$$). You have not listed any of these definitive tests. A shrinking spleen size is a good sign no matter what, but many illnesses could cause the labs your son has: even malaria, other parasites, hepatitis, or congenital inborn errors. Your son deserves more tests. ...Read more

Why does mono only affect the spleen?

Why does mono only affect the spleen?

It doesn't: Mononucleosis is an infection by the epstein-barr virus. The infection is fought off by the body's immune system, composed of white blood cells and other proteins. The spleen is similar to a giant lymph node and will swell up as it fights the virus, as do the neck lymph nodes. The spleen is mentioned because it's location and thin covering makes it vulnerable to trauma and rupture with hemorrhage. ...Read more

In general the younger you are the faster. If your left side is still very sore it may be worth checking with your doctor to make sure is really your spleen that hurts or even consider an ultrasound. ...Read more

I kissed my girlfriend 5 weeks after having mono (did not know I had it at time) and she's already had it. Can she get it again?

No worries: Infectious mononucleosis (called glandular fever in some countries) is the result of infection with a virus called Epstein Barr virus (EBV). Once recovered from mono, people are immune to new EBV infections. Your partner can't get it again -- of course assuming her previous diagnosis of mono was correct. ...Read more

Is it possible for your spleen to enlarge as Mono is heading out of your system? It wasn't enlarged before but I'm worried. Is that not how it works?!

Peaks early: With this disorder, you usually see this side effect by the end of the first week of symptoms (which is when they come in for diagnosis) with a gradual decline over the course of the illness. By three weeks in I am seldom ever able to feel an enlarged spleen, even on kids who had it earlier. ...Read more
