Why C-Section Babies More Likely To Develop Allergies

This study gives us one more reason that C-section is not good for mother but also not good for kids.

What is C section?

Cesarean delivery — also known as a C-section — is a surgical procedure used to deliver a baby through an incision in the mother's abdomen and a second incision in the mother's uterus.
A C-section might be planned ahead of time if you develop pregnancy complications or you've had a previous C-section and aren't considering vaginal birth after cesarean (VBAC). Often, however, the need for a first-time C-section doesn't become obvious until labor is under way.
If you're pregnant, knowing what to expect during a C-section — both during the procedure and afterward — can help you prepare

Why it's done?

Sometimes a C-section is safer for you or your baby than is a vaginal delivery. Your health care provider might recommend a C-section if:
Your labor isn't progressing.
Stalled labor is one of the most common reasons for a C-section. Perhaps your cervix isn't opening enough despite strong contractions over several hours — or the baby's head is simply too big to pass through your birth canal.
Your baby isn't getting enough oxygen
If your health care provider is concerned about your baby's oxygen supply or changes in your baby's heartbeat, a C-section might be the best option.
Your baby is in an abnormal position
A C-section might be the safest way to deliver the baby if his or her feet or buttocks enter the birth canal first (breech) or the baby is positioned side or shoulder first (transverse).
You're carrying twins, triplets or other multiples
When you're carrying multiple babies
 it's common for one or more of the babies to be in an abnormal position. In this case, a C-section is often safer.
There's a problem with your placenta
If the placenta detaches from your uterus before labor begins (placental abruption) or the placenta covers the opening of your cervix (placenta previa),
 C-section might be the safest way to deliver the baby
There's a problem with the umbilical cord
A C-section might be recommended if a loop of umbilical cord slips through your cervix ahead of your baby or if the cord is compressed by the uterus during contractions.
You have a health concern
Your health care provider might suggest a C-section if you have a medical condition that could make labor dangerous, such as unstable heart disease or high blood pressure. In other cases, a C-section might be recommended if you have an infection that could be passed to your baby during vaginal delivery — such as genital herpes or HIV.
Your baby has a health concern
A C-section is sometimes safer for babies who have certain developmental conditions, such as excess fluid in the brain (hydrocephalus).
You've had a previous C-section
Depending on the type of uterine incision and other factors, it's often possible to attempt a vaginal delivery after a previous C-section. In some cases, however, your health care provider might recommend a repeat C-section.
Recovery from a C-section takes longer than does recovery from a vaginal birth.
And like other types of major surgery, C-sections also carry a higher risk of complications.

Risks to your baby include:

Breathing problems
Babies born by C-section are more likely to develop transient tachypnea — a breathing problem marked by abnormally fast breathing during the first few days after birth. C-sections done before 39 weeks of pregnancy or without proof of the baby's lung maturity might increase the risk of other breathing problems, including respiratory distress syndrome — a condition that makes it difficult for the baby to breathe.
Surgical injury
 Although rare, accidental nicks to the baby's skin can occur during surgery.
Risks to mother
Inflammation and infection of the membrane lining the uterus
This condition — known as endometritis — can cause fever, foul-smelling vaginal discharge and uterine pain.
Increased bleeding
 You're likely to lose more blood with a C-section than with a vaginal birth. Transfusions are rarely needed, however.
Reactions to anesthesia
Adverse reactions to any type of anesthesia are possible. After an epidural or spinal block — common types of anesthesia for C-sections — it's rare, but possible, to experience a severe headache when you're upright in the days after delivery.
Blood clots
The risk of developing a blood clot inside a vein — especially in the legs or pelvic organs — is greater after a C-section than after a vaginal delivery. If a blood clot travels to your lungs (pulmonary embolism), the damage can be life-threatening. Your health care team will take steps to prevent blood clots. You can help, too, by walking frequently soon after surgery.

What are Babies Allergies?

It’s important to introduce baby to new foods gradually, and one at a time, in case of food allergies. Otherwise, you’ll have trouble tying an allergy to a specific new food. For example, if you give your baby three new foods over the course of a day and she develops an allergic reaction, you won’t know which of the foods provoked it.
It doesn’t matter all that much which foods you introduce to your baby, or which order you introduce them in, as long as the foods you are offering are healthy and well-balanced. But each time you offer a new food, you should wait three to five days before adding another to the menu. Don’t eliminate all the other foods your baby is already eating during that time -- just don’t add anything else new.

The Top 8 Allergenic Foods

With each new food, you’ll want to be on the lookout for allergic reactions. There are more than 160 allergenic foods, but these eight foods and food groups are the culprits 90% of the time. You may want to wait until baby is older to try some of these foods, especially peanuts. In fact, many experts suggest waiting until your child is 3 before trying peanuts. Ask your pediatrician if you have any questions about a food.
 
Milk
Egg
Peanuts
Tree nuts (such as walnuts or almonds)
Fish
Shellfish
Soy
Wheat

Food Allergy Symptoms to Watch for in Your Baby

Food allergy symptoms usually appear very soon after the food is eaten -- within a few minutes to a couple of hours. If you’re introducing a new food to your baby, keep an eye out for these symptoms:
Hives
Flushed skin or rash
Face, tongue, or lip swelling
Vomiting and/or diarrhea
Coughing or wheezing
Difficulty breathing
Loss of consciousness

Severe Food Allergy Symptoms: When to Call 911

If your baby is having trouble breathing, has swelling on her face, or develops severe vomiting or diarrhea after eating, don’t take time to call your pediatrician. Call 911 immediately. Severe allergic reactions can be fatal very quickly

New Research-C-Section Babies 5 Times More Likely To Develop Allergies


C-section babies are five times more likely to develop allergies by age two than those born naturally. The finding came from a new study conducted by researchers from Henry Ford Hospital and was presented at the American Academy of Allergy, Asthma, and Immunology yearly meeting in San Antonio.

 The findings coincide with previous research which demonstrated that babies born by C-section are more likely to have asthma than babies delivered naturally. A different report showed that caesarean section babies have an increased risk of food allergies and diarrhea during their first year of life. The new report indicated that C-section (cesarean section) babies are more vulnerable to allergies. They found that the chance of developing allergies for C-section babies is five times greater than for those born naturally when exposed to high levels of common allergens in the home, including those from cats, dogs, and dust mites. Leading author Christine Cole Johnson, Ph.D., MPH, chair of Henry Ford Department of Health Sciences, said, “This further advances the hygiene hypothesis that early childhood exposure to microorganisms affects the immune system's development and onset of allergies. We believe a baby's exposure to bacteria in the birth canal is a major influencer on their immune system.
In the gastrointestinal tract of babies born by C-section, there is a pattern of "at risk" microorganisms that may cause them to be more vulnerable to developing the antibody Immunoglobulin E, or IgE, when in contact with allergens, according to Dr. Johnson. It is known that IgE is associated with the development of asthma and allergies. For the purpose of the study, the experts at Henry Ford set out to assess the role of early exposure to allergens and analyze how this exposure has an impact on the link between C-section and the development of IgE. A total of 1,258 newborns were involved in the investigation from 2003 until 2007 and were assessed at 4 different times: at one month old, six months, one year, and two years.

The researchers gathered data from:
The baby's umbilical cord and stool
Breast milk
Household dust
Blood samples from the baby's mother and father
Family history of allergy or asthma
Household pets
Tobacco smoke exposure
Medication use
Baby illnesses
Pregnancy variables
The research received funding from Henry Ford Hospital and National Institute of Allergy and Infectious Diseases.
