Does running and gym exercise increase existing lipoma growth or does it produce more lipomas in body?

Running and gym exercise should not cause existing lipomas to grow or produce new lipomas.  With having existing lipomas, running would be fine to keep your body fit.  

Thank you for your excellent question.  Neither running, nor gym work, will affect your current lipoma or create new ones.  Hope this helps. 

Feel free to run at the gym without worrying about the effect on lipomas. No one knows exactly what causes lipomas (fatty tumors under the skin) but they are very common. Some people have multiple -10 or 100 or more, which can run in families and therefore likely related to a genetic predisposition. Lipomas need not be removed unless they bother you. IF you have multiple, I recommend you only remove those that concern you, because in those patients with alot of lipomas, new ones always show up regardless of your lifestyle, food choices, weight or exercise routine. Good luck and take care.
