The questions HR teams and managers actually ask, answered plainly. Educational guidance — not legal advice.

Understanding the condition

Is this just severe morning sickness?

No. Hyperemesis Gravidarum is a distinct pregnancy complication involving persistent vomiting, dehydration, weight loss, and inability to keep down food or fluids. It frequently requires medication, and often intravenous fluids or hospital admission.

Will it be over at twelve weeks?

Not reliably. Many women improve in the second trimester, but for a significant number HG continues throughout pregnancy. Plan for uncertainty rather than a date.

Could stress or anxiety be causing it?

No. Current understanding is that HG is biologically driven. Attributing it to stress or attitude is both inaccurate and damaging.

How common is it?

It affects an estimated 0.3 to 3 percent of pregnancies — meaning most mid-sized employers will encounter it.

Process and documentation

Can we ask for medical documentation?

You can generally request proportionate documentation confirming a pregnancy-related condition and recommended adjustments. Requiring a note for each individual absence is disproportionate and counterproductive.

She cannot give a return date. What do we do?

Plan in two-week blocks with scheduled reviews rather than waiting for certainty that will not arrive.

Do we have to grant everything she asks for?

No. The expectation is a genuine, documented effort to find workable adjustments — including offering alternatives where a specific request is not operationally possible, and explaining why.

Should we wait for the paperwork before adjusting anything?

No. Interim measures cost little and prevent avoidable absence, escalation, and resignation.

Managing the team

What do we tell colleagues?

Only what she has approved — usually that arrangements have temporarily changed. Her diagnosis is not team information.

Colleagues are covering extra work and resenting it. Is that our problem?

Yes, and it is yours to manage. Redistribute formally, acknowledge the extra load, and do not let her become the subject of team discussion.

Can absence affect her performance rating?

It should not. HG-related absence should be excluded from ratings, attendance triggers, and bonus calculations.

Practical questions

What accommodations actually help most?

Flexible or later start times, remote work where possible, a private space to rest, relief from food-related and travel duties, and generous handling of appointments. See the Workplace Accommodation Worksheet.

She keeps apologizing and working through it. What should we do?

Tell her explicitly to stop. Presenteeism in HG leads to worse outcomes and longer absence. Remove the pressure in writing.

What about her return?

Recovery does not end at delivery. Plan a phased return with reviews — see the Return-to-Work Planning Guide.

What if we get this wrong?

Say so, fix it, and continue. Employees remember whether you tried, not whether you were perfect.

The one-sentence summary

Believe her, adjust early, write it down, review it every two weeks, and confirm her job is safe. Those five things account for most of what good looks like.

THON Reflection

Supporting one woman through Hyperemesis Gravidarum well teaches an organization how to support everyone — because it forces you to design around a person instead of a policy.
