If HG continued past mid-pregnancy, did you experience complications during delivery related to your poor health such as a strained ligaments/joints, pelvic floor damage, prolonged or weak pushing, fainting, low blood pressure, low pain tolerance, forceps/assisted delivery, broken bones, nerve damage, low amniotic fluid, fetal problems due to difficult delivery, etc.?

Possible Complications

Numerous complications can result from HG if it is severe, not adequately treated or there is a delay in medical interventions. However, most women have only minor complications such as muscle atrophy, fatigue, constipation, sleep disturbance, and gastric (stomach) irritation. Long-term health problems are not yet defined and have not been studied by researchers thus far. Most seem to be related to the severity of vomiting, thus women with excessive, uncontrolled vomiting for months will have a greater chance of complications. If women with HG are given early medical care sufficient to manage their symptoms and minimize nutritional deficiencies, both mother and child will likely be healthy now and in the future.

However, some research is suggesting that prolonged stress, malnutrition and dehydration in the mother can potentially put the unborn child at risk for chronic disease (e.g. diabetes, heart disease) in later life. This has been termed "fetal programming" by researchers and is a relatively new field of study. Early, moderate weight loss (less than 5-10% of her pre-pregnancy weight) by a mother does not mean a child will necessarily have diseases in adult life, rather, severe or prolonged malnutrition as a pregnancy progresses may increase the risk of disease for the child later. Other factors such as the child's later health habits (e.g. smoking, obesity, diet) also determine if they will develop chronic health conditions. This underscores the importance of providing a mother with the care she needs, for her health and that of her baby.

Severe HG

Weight gain in the mother and adequate birth weight of the child are used to determine if nutrition is sufficient for the baby. Adverse effects of mild HG on the baby do not seem to be common, however, if moderate or severe, there is cause for concern. Severe HG usually causes the mother to rapidly lose an excessive amount of weight, continue to lose weight or gain slowly during the second half of pregnancy, and/or results in a low fetal birth weight or delayed development. Women with prolonged or severe HG are also at greater risk for preterm labor and high blood pressure (pre-eclampsia), which may be related to malnutrition. Medical professionals experienced in caring for high-risk pregnancies or women with HG are critical in ensuring adequate care of these mothers. If a woman shows signs of severe HG and her care seems inadequate or she is not improving, a second opinion is often necessary. In most cases, medications and nutritional therapies can ease symptoms and allow both mother and child to avoid serious complications.

Signs of Severe HG:

  • Debilitating, chronic nausea 
  • Frequent vomiting of bile or blood
  • Chronic ketosis and dehydration
  • Muscle weakness and extreme fatigue
  • Medication does not stop vomiting/nausea
  • Inability to care for self (shower, prepare food)
  • Loss of over 5-10% of your pre-pregnancy weight
  • Weight loss (or little gain) after the first trimester
  • Inability to eat/drink sufficiently by about 14 weeks
