Calculator inputs
Use the fields below to estimate how strongly food aversions may be affecting daily eating, hydration, and nutrition coverage.
Example data table
| Profile | Week | Intensity | Days per week | Fluid tolerance | Tolerated groups | Weighted aversion score | Interpretation |
|---|---|---|---|---|---|---|---|
| Mild morning aversion | 10 | 3 | 2 | 90% | 5 | 29 | Mild burden with lower daily disruption. |
| Smell-triggered mixed pattern | 18 | 6 | 5 | 70% | 4 | 68 | High burden with narrowing meal flexibility. |
| Severe intake restriction | 9 | 8 | 7 | 45% | 2 | 100 | Severe burden with urgent hydration concern. |
Formula used
This calculator uses a weighted scoring approach. Higher scores mean stronger disruption to eating, hydration, or meal variety.
The weighting emphasizes practical issues that commonly affect meal success: intensity, frequency, food group losses, vomiting, and reduced fluid tolerance.
How to use this calculator
- Enter your current gestational week and symptom levels.
- Estimate how many days each week aversions disrupt eating.
- Add skipped meals, vomiting episodes, and fluid tolerance percentage.
- Check the food groups that still feel manageable.
- Mark common triggers and count any extra trigger foods.
- List safe foods that usually work for you.
- Click Calculate to show the result below the header.
- Use the score, graph, and suggestions to plan gentler meals and decide when to ask for medical guidance.
FAQs
1) Is this a medical diagnosis?
No. It estimates symptom burden and practical intake strain from your entries. It cannot diagnose hyperemesis, allergies, or fetal concerns.
2) What does the weighted aversion score mean?
It summarizes how strongly aversions affect daily eating. Higher scores suggest more disruption from nausea, smell sensitivity, skipped meals, and limited safe foods.
3) Why does fluid tolerance matter so much?
Low fluid tolerance raises hydration risk quickly. Even when food intake is limited, keeping fluids down is a major practical priority.
4) What counts as a safe food?
A safe food is one you can usually tolerate without major nausea, gagging, or aversion. Bland, cool, and familiar foods often fit this category.
5) Should I worry if only a few food groups work?
Fewer tolerated groups can narrow nutrition coverage. That does not always mean an emergency, but it is worth discussing if it persists.
6) When should I contact my clinician quickly?
Reach out promptly if you cannot keep fluids down, vomiting is frequent, dizziness worsens, or you notice meaningful recent weight loss.
7) Can I use this score to track changes over time?
Yes. Repeating the same inputs every few days can help you notice whether symptoms, hydration, or meal flexibility are improving or narrowing.
8) Does a high score mean something is wrong with the baby?
No. A high score reflects your current eating difficulty, not a direct fetal diagnosis. It signals that you may need more support.
