This case study describes a pregnant woman who developed a serious blood clotting condition called HELLP syndrome, which is common in pregnancy. However, doctors discovered she also had two hidden health issues: severe vitamin B12 deficiency and a genetic condition affecting her red blood cells. These additional problems made her condition much more dangerous and complicated her treatment. The story shows why doctors need to look carefully for other health problems when pregnant women develop blood clotting disorders, especially if they’ve had weight-loss surgery. Understanding these connections helps doctors provide better care and protect both mother and baby.

The Quick Take

  • What they studied: A single pregnant patient who developed a serious blood clotting condition and what other health problems were discovered during her care
  • Who participated: One pregnant woman who had previously undergone weight-loss surgery and developed severe complications during pregnancy
  • Key finding: The patient had HELLP syndrome (a pregnancy-related blood clotting disorder) combined with severe vitamin B12 deficiency and a genetic red blood cell condition, which together created a life-threatening situation requiring early delivery
  • What it means for you: If you’re pregnant and develop symptoms like severe headaches, vision changes, or unusual bruising, doctors should check for multiple possible causes, not just assume it’s a standard pregnancy complication. This is especially important if you’ve had weight-loss surgery.

The Research Details

This is a case report, which means doctors documented the medical story of one patient in detail. The patient was a pregnant woman who developed HELLP syndrome (a condition where pregnancy causes blood clots to form in small blood vessels, damaging the liver and reducing platelets, which are cells that help blood clot). During her hospital care, doctors performed many blood tests and imaging studies to understand what was happening. They discovered she had severe vitamin B12 deficiency and a genetic condition called glucose-6-phosphate dehydrogenase deficiency that affects how red blood cells work. The doctors tracked her symptoms, lab results, and how she responded to treatment over time.

Case reports are important because they describe unusual or complex situations that doctors might not see often. By documenting this patient’s story in detail, other doctors can learn to recognize similar patterns and know what tests to order. This helps improve care for future patients with similar complications.

This is a single case report, which provides detailed information about one patient but cannot prove something works for everyone. Case reports are the lowest level of research evidence because they describe just one person’s experience. However, they’re valuable for alerting doctors to unusual combinations of conditions and highlighting the need for thorough testing. The findings cannot be generalized to all pregnant women, but they provide important clinical insights.

What the Results Show

The patient developed HELLP syndrome early in her pregnancy (before 34 weeks), which is unusual because HELLP typically occurs later. Her condition worsened rapidly, and she also developed PRES (posterior reversible encephalopathy syndrome), a brain condition that causes severe headaches, vision problems, and seizures. Blood tests revealed she had severe vitamin B12 deficiency, which can worsen blood clotting problems and cause neurological symptoms. She also had glucose-6-phosphate dehydrogenase deficiency, a genetic condition that makes red blood cells fragile and prone to breaking down. Because her condition deteriorated so quickly and posed serious risks to her life, doctors decided to deliver the baby early to stop the pregnancy and prevent further complications.

The combination of HELLP syndrome, PRES, severe B12 deficiency, and the genetic red blood cell condition created a medical emergency. The patient’s prior weight-loss surgery likely contributed to her B12 deficiency because that surgery affects how the body absorbs certain nutrients. This case shows that multiple health problems can occur together and make each other worse. The rapid worsening of symptoms despite standard treatment for HELLP suggested that other conditions were involved.

HELLP syndrome and preeclampsia are well-known pregnancy complications, and delivery is the standard treatment. However, this case is unusual because the patient had additional hidden conditions that made her situation more dangerous. Previous research has shown that people with genetic red blood cell conditions may have worse outcomes during pregnancy, and severe B12 deficiency can complicate blood clotting disorders. This case demonstrates that doctors should think about these possibilities, especially in patients with unusual presentations or rapid deterioration.

This is a single case report about one patient, so the findings cannot be applied to all pregnant women. We don’t know how common this combination of conditions is or whether the same approach would work for other patients. The case doesn’t prove that weight-loss surgery always leads to these complications, only that it may increase the risk of B12 deficiency. Doctors cannot conduct controlled experiments with pregnant patients for safety reasons, so case reports are often the only way to document rare or unusual situations.

The Bottom Line

If you’re pregnant and develop severe headaches, vision changes, upper abdominal pain, or unusual bruising, seek immediate medical care. If you’ve had weight-loss surgery, tell your doctor because you may need B12 monitoring during pregnancy. Doctors should perform comprehensive blood testing when pregnant patients develop blood clotting complications, rather than assuming it’s a standard pregnancy condition. These recommendations are based on this single case and clinical experience, not large studies.

Pregnant women, especially those who have had weight-loss surgery, should be aware of these warning signs. Doctors caring for pregnant patients should consider this case when evaluating women with unusual or rapidly worsening blood clotting complications. Family members of patients with genetic red blood cell conditions should discuss pregnancy planning with their doctors.

Serious complications like HELLP syndrome and PRES develop rapidly, sometimes over hours to days. This is why immediate medical attention is critical. If you have risk factors, monitoring should begin early in pregnancy, not after symptoms appear.

Want to Apply This Research?

  • If you’ve had weight-loss surgery and are pregnant or planning pregnancy, track your B12 levels quarterly and note any symptoms like unusual fatigue, tingling in hands/feet, or severe headaches. Log these in your health app with dates.
  • Schedule a pre-pregnancy consultation with your doctor if you’ve had weight-loss surgery to discuss B12 supplementation and genetic screening. During pregnancy, attend all scheduled appointments and report new symptoms immediately rather than waiting.
  • Set monthly reminders to check in with your healthcare provider about B12 status and pregnancy symptoms. Use the app to track blood pressure readings, headaches, vision changes, and abdominal pain—report any concerning patterns to your doctor immediately.

This case report describes one patient’s experience and cannot be applied to all pregnant women. If you are pregnant or planning pregnancy, especially if you’ve had weight-loss surgery or have a family history of genetic blood disorders, discuss your individual risk factors with your healthcare provider. Do not use this information to self-diagnose or self-treat. Seek immediate medical attention if you experience severe headaches, vision changes, abdominal pain, or unusual bruising during pregnancy.
