Dr. Wei Di Wang

About

NUWA places a weight management clinic inside its reproductive medicine department rather than treating body weight as somebody else’s problem, and the physician attached to it is not a fertility doctor. Dr. Wei Di Wang is part-time attending physician in the Reproductive Medicine and Weight Management Department, and the substantive hospital career runs at a separate institution, St. Mary’s Hospital in Luodong. The clinical overlap is a specific one: weight and metabolic state change ovulation, the response to stimulation medication, and the risk profile of a pregnancy, and they affect semen parameters on the male side too.

The St. Mary’s appointments are three at once. Director of the outpatient department, which is an administrative post over how clinic services run. Attending physician in the division of gastroenterology and hepatology. And specialist in obesity medicine, held alongside rather than instead of the liver and gut work. That pairing matters for this patient group because obesity is rarely alone: fatty liver, disturbed glucose and lipid values and raised blood pressure travel with it, and all of them belong to the organs a gastroenterologist watches.

The training is internal medicine with an endoscopy and interventional overlay. Taipei Municipal Wan Fang Hospital supplied resident physician and then chief resident in the department of internal medicine, plus a research fellowship in thermal ablation of liver tumours. Endoscopy research fellowships followed at Taipei Medical University Hospital and at Saitama Medical University International Medical Center in Japan. The medical qualification is a Taipei Medical University School of Medicine degree. Assessment is done with blood tests and abdominal ultrasound, and referral for endoscopic weight-loss treatment belongs to the work, which is the same skill set that produced the endoscopy fellowships.

Clinical Expertise

• Weight planning before conception: setting a target weight and a timetable for men and women who are trying to conceive, so that the reduction and the attempt to pregnancy are sequenced rather than competing with each other. The named groups are people preparing for pregnancy, adults and adolescents.
• Obesity assessment and stepped treatment: choosing between diet change, lifestyle intervention and medication — oral drugs and injectable weight-loss agents, with Ozempic given as the example — and moving up the ladder only when the lower tier has not reached the target.
• Weight management in PCOS: insulin resistance and weight gain are part of the syndrome for many patients, and ovulation that will not respond to induction medication often sits behind the metabolic problem rather than beside it.
• Fatty liver, metabolic syndrome and obesity-related risk: blood work and abdominal ultrasound to establish liver fat, glucose and lipid values and blood pressure, then a reading of what those mean for conceiving and for a pregnancy’s safety.
• Abdominal ultrasound as an assessment instrument: imaging used to document liver and abdominal organ status, which makes the metabolic picture something measured rather than inferred from a body mass index alone.
• Endoscopic weight-loss treatment assessment and referral: judging when drug and lifestyle treatment has gone as far as it usefully can and a procedural or surgical route belongs in the discussion, then arranging that referral.
• Internal medicine and gastroenterology: the general medical layer underneath the weight work, covering patients whose obesity questions arrive together with liver, gut or metabolic disease.

Why Choose Dr. Wang

The metabolic line is managed inside the fertility clinic. Weight and metabolic questions are usually sent out of a fertility practice to another department or another building, and the two records then have to be reconciled by the patient. Here the weight clinic sits within the reproductive medicine department, so a reduction plan, a medication review and the start date of a cycle are set on one timetable instead of two.

A gastroenterologist reads the liver. Fatty liver disease is a common finding in obesity assessment and one that sits outside the usual scope of a fertility practice, since it needs imaging, blood interpretation and follow-up in the same consult. The attending post in gastroenterology and hepatology at a general hospital is what makes that assessment a specialist reading.

Measurement rather than estimation. Blood tests and abdominal ultrasound are named as the method of assessment, which is the difference between a weight target and a documented metabolic picture: two patients with the same body mass index can have very different liver fat, glucose and lipid values, and only the tests separate them.

The full treatment ladder is on the list. Diet, lifestyle, oral medication, injectable agents, and assessment for endoscopic procedures are all named, in that order. It describes how a case is actually escalated, and it means a patient who does not want medication can start at the lifestyle tier without the plan collapsing.

General internal medicine underneath the weight work. The training path runs resident physician and chief resident in the department of internal medicine at Taipei Municipal Wan Fang Hospital before the subspecialty and research posts, so a patient whose obesity picture arrives with hypertension, thyroid questions or unrelated medical problems is being read by someone whose base specialty is general medicine rather than reproductive care.

Professional Affiliations

Appointments held: part-time attending physician, Reproductive Medicine and Weight Management Department, NUWA Fertility Center; director of the outpatient department, attending physician in the Division of Gastroenterology and Hepatology, and obesity medicine specialist at St. Mary’s Hospital Luodong. Earlier posts: resident physician and chief resident in internal medicine at Taipei Municipal Wan Fang Hospital, research fellow in liver tumour thermal ablation at the same hospital, research fellow in endoscopy at Taipei Medical University Hospital, and research fellow in endoscopy at Saitama Medical University International Medical Center in Japan. Degree: School of Medicine, Taipei Medical University.

The two research fellowships in endoscopy, one in Taipei and one in Japan, sit in the same subspecialty as the current hospital appointment, and the thermal ablation fellowship belongs to the interventional side of liver disease. Medical training itself was Taipei Medical University’s School of Medicine. The NUWA role is part-time, so consultation times are set by the center.

Suitable For

Weight and metabolic work while trying to conceive: losing weight and timing a pregnancy pull in opposite directions, since the reduction takes months a patient may not have. The named expertise begins with men and women preparing for pregnancy, which is the group where the timetable has to be built first.

PCOS with insulin and weight problems: induction medication works better when insulin resistance is addressed at the same time, and weight is one of the levers available. Weight management for polycystic ovary syndrome and related metabolic conditions is a listed area.

Fatty liver or metabolic syndrome with infertility: liver fat, glucose and lipids bear on pregnancy safety as well as on conception, and they are assessed by blood test and ultrasound by a physician whose hospital post is in hepatology.

Evaluating weight-loss medication or injections: whether a drug tier is appropriate, and how long before conception it should be stopped, is a decision that depends on the individual metabolic picture rather than on a label. Oral and injectable options appear on the list, alongside the non-drug tiers they are added to.

Body preparation before an IVF cycle: raised body mass affects stimulation dosing, anesthetic risk at retrieval, and miscarriage rate, so improving metabolic state before a cycle starts changes the cycle itself. Because the clinic sits inside the reproductive department, the preparation period can be coordinated with the physician who will run the treatment.

Adult and adolescent weight planning together: the listed scope covers adolescents as well as adults, which suits families where a younger member has a weight or metabolic problem and a parent is simultaneously in a fertility workup.
