Mesenteric Lymph Nodes - #18589

A few months ago, my younger brother started complaining of severe stomach pain that would come and go. At first, we thought it was just a digestion issue, but then he also developed a mild fever, nausea, and loss of appetite. The doctor advised an ultrasound, and that’s when we found out that his mesenteric lymph nodes were swollen. I had never even heard of them before! Doctor, could you please explain what exactly the mesenteric lymph nodes do in the body? Why do they get swollen in some people? The doctor mentioned something about a viral or bacterial infection, but my brother didn’t have any major illness before this. What kind of infections specifically lead to swollen mesenteric lymph nodes? One thing that confused me was how similar his symptoms were to appendicitis. We were really scared because the pain was on the right side of his abdomen, just like in appendicitis. Are swollen mesenteric lymph nodes often mistaken for appendicitis? How can we tell the difference between the two? I also want to know how Ayurveda views swollen mesenteric lymph nodes. Are they connected to digestion problems, or is it more of an immune system issue? The doctor prescribed antibiotics, but my brother didn’t feel immediate relief. Are there any Ayurvedic treatments that can help reduce inflammation in the mesenteric lymph nodes naturally? Another thing I’ve read is that some people get chronic swelling of the mesenteric lymph nodes. What could be the reasons behind this? Does diet play a role in keeping these lymph nodes healthy? If so, what are the best foods and herbs to support them? Also, can swollen mesenteric lymph nodes lead to any long-term issues? My brother recovered after a few weeks, but he still gets mild stomach discomfort sometimes. Could it be a sign that the lymph nodes are still inflamed? How can we check if they have returned to their normal size? Lastly, I am curious to know if stress or lifestyle habits can contribute to swollen mesenteric lymph nodes. My brother is a very active teenager, but he sometimes eats a lot of junk food. Could poor eating habits trigger this condition? And if someone has already had it once, are they more likely to get it again? Would really appreciate your insights on mesenteric lymph nodes and their Ayurvedic treatment.
