This photo shows why a baby spits up or regurgitates when on their back or in the infant car seat. You can see that the food easily can come up the esophagus. The best position would be to hold the baby upright for at least a hour after feeding to allow the food to leave the stomach
Not overfeeding a newborn infant also helps since an average newborn takes anywhere between 2-3 ounces of formula every 2-3 hours or 24 ounces a day. They have a sucking reflex and can take much more if you let them, however, their small stomachs would regurgitate the excess before it would have a chance to empty.
I recently saw a patient with a history of Lyme disease and and a bullseye rash. He had it 4 years ago and was treated with antibiotics. He came to me because of nausea, diarrhea, belly cramps. Many people are unaware that when you are bit by a tic, you can now get a number of other infections such as bartonella ( the bacteria that causes cat scratch fever) and mycoplasma species ( cause of chronic fatigue ), Anaplasma, and babesia ( a parasite). Its not just lyme alone, which makes the picture of what is going on very complicated. Sometimes the labs dont confirm what you suspect and the physician has to go based on symptoms.
Lyme is called the great imitator cause it may mimic over 300 other diseases including, crohn’s, celiac, thyroiditis, multiple sclerosis, rheumatoid arthritis and lupus ( just to name a few). Bartonella also causes enlarged lymph nodes and may mimic appendicitis. These infections may be associated with a rash which resembles stretch marks but occurs in areas where stretch marks dont occur.
My patient had a thorough evaluation by two other Gastro specialist as well as MRI of the brain, While there was no evidence of inflammation, or active infection, these infections often cause the immune system to be activated and chemical from the immune system can affect the body in different ways. I believe in this case, his brain was affecting his gut, causing cramps and diarrhea and vomiting. His endoscopy and colonoscopy were entirely normal, ruling out other causes of nausea vomiting and diarrhea.
Another point to make is– people can get bit more than once with a tic. There are different species of infections carried by tics. One treatment and success doesnt preclude getting bit again and new symptoms or recurring symptoms. Seek out a health professional who will listen to you, believe what you are telling you, who wont dismiss you and has the persistance to pursue and refer if he doesnt know what is going on.
Notice from the three pictures that the baby on the belly is least likely to reflux ( unless overfed) being on the back or in an infant car seat promotes reflux -especially since the valve between the stomach and esophagus is not fully developed in newborns
