## Short answer

IBS looks much the same in women as in men: belly pain linked to bowel movements, with diarrhea, constipation or both, and often bloating. Research finds that women are more likely to have IBS, tend to report more pain and constipation than men, and often have more symptoms around their periods. Other conditions can look alike, so new, severe or unexplained symptoms need a doctor, not a diary.

- **Choose this if:** A symptom diary kept for a few weeks is enough to start with if your symptoms fit the usual IBS pattern and no warning sign is present.
- **Choose the other option if:** Gutli helps you keep meals and symptoms in one timeline once a doctor has ruled out other causes, and it can produce a report to bring to your appointment.

## Side by side

| | IBS | Endometriosis |
| --- | --- | --- |
| Pain linked to bowel movements | Yes, it often eases or worsens after a bowel movement | Partly, pain when you poo is one possible symptom |
| Symptoms tied to your period | Yes, women often have more symptoms during periods | Yes, with severe period pain or heavy bleeding |
| Pelvic pain | Partly, listed among the other symptoms by the NHS | Yes, in the lower tummy, back and pelvis |
| Pain during or after sex | Not stated by NIDDK or the NHS | Yes, listed by the NHS |
| Diagnosed with a single test | No, blood and stool tests only rule out other conditions | Partly, a laparoscopy can confirm it, with ultrasound or MRI as other tests |

## The core symptoms

NIDDK, part of the US National Institutes of Health, says the most common symptoms of irritable bowel syndrome (IBS) are pain in the abdomen, often related to bowel movements, and changes in bowel movements: diarrhea, constipation or both. Other symptoms can be bloating, the feeling that you have not finished a bowel movement, and whitish mucus in the stool.

The NHS describes stomach pain or cramps that are usually worse after eating and better after a bowel movement, plus bloating, diarrhea and constipation. Symptoms can come and go, with better days and flare-ups, and can be set off by food or drink. The NHS also lists wind, nausea, tiredness, backache, bladder problems and pelvic pain as other possible symptoms.


## Do women have different symptoms?

NIDDK says women are up to two times more likely than men to develop IBS. A 2010 meta-analysis in Alimentary Pharmacology and Therapeutics pooled 22 studies. Women were more likely to report abdominal pain and constipation-related symptoms (relative risk 1.12 for each), and men with IBS were more likely to report diarrhea-related symptoms. The authors call the differences modest.

In practice, that means the list of symptoms is the same, and the mix may lean toward pain and constipation in women. Your own pattern matters more than an average.


## Periods and hormones

NIDDK says women with IBS often have more symptoms during their periods. The same meta-analysis reviewed 13 studies and found that both women with IBS and healthy women reported more IBS-type symptoms during menses than in other phases of the cycle.

The authors say studies suggest that female sex hormones influence the severity of symptoms, but that more studies are needed, and they found too little data to say what menopause or hormone supplements do. Our advice is to mark your period dates next to your symptoms, so that you and your doctor can see whether a cycle pattern exists for you.


## Conditions that look alike

The NHS says endometriosis symptoms can be similar to other conditions, including irritable bowel syndrome, and that diagnosis can take a long time. Its symptoms include severe period pain, heavy periods, pelvic pain, pain when you poo or pee, pain during or after sex and extreme tiredness.

The NHS lists ovarian cancer symptoms of frequently, roughly 12 or more times a month, having a swollen tummy or bloating, pelvic pain, feeling full quickly after eating, or needing to pee more often. It says these symptoms are very common and caused by many conditions, but that they should still be checked by a doctor because early finding makes cancer more treatable. Our advice: bloating that is new, frequent and does not settle deserves that check, even if you have always had a sensitive gut.


## Signs that need a doctor

NIDDK says certain symptoms may suggest another health problem instead of IBS: anemia, bleeding from the rectum, bloody or black tarry stools, and weight loss. The NHS advises urgent help for losing a lot of weight for no reason, bleeding from the bottom or bloody diarrhea, a hard lump or swelling in the tummy, or shortness of breath with palpitations and unusually pale skin. Our advice: in the US, call your clinician the same day or use urgent care for these, and call 911 for heavy bleeding, fainting or severe pain. The details are in our guide to IBS red flags.

The NHS also advises seeing a doctor if you think you have IBS and symptoms have lasted over 4 weeks. There is no single test for IBS: NIDDK says doctors look for a pattern of pain with two or more of three features (relation to bowel movements, change in how often you go, change in how stools look), and the NHS says blood and stool tests may be used to rule out conditions such as celiac disease and inflammatory bowel disease. The American College of Gastroenterology guideline suggests a celiac blood test for people with IBS and diarrhea symptoms, and a fecal calprotectin test to rule out inflammatory bowel disease.


## What to track

The NHS suggests writing down details of your symptoms before your appointment, including when you get them, how often, how long, and whether they follow certain foods. The fields below are our own suggestions built on that advice.

- Date and time of each episode, and how long it lasted.
- Pain on a 0 to 10 scale and where it was: upper, lower or one side.
- Bloating, and whether it eased after a bowel movement.
- Stool type, using the Bristol chart, and how many times you went.
- Meals and drinks in the hours before, including alcohol and caffeine.
- Period start and end dates, and any heavy bleeding or pain during sex.
- Stress, sleep and any new medicines or antibiotics.

## Frequently asked questions

### What are the first signs of IBS in women?

Belly pain that is related to bowel movements, together with a change in them: diarrhea, constipation or both. Bloating is common, according to NIDDK.

### Do women get different IBS symptoms than men?

The symptoms are the same, but a 2010 meta-analysis found women reported more abdominal pain and constipation, and men more diarrhea. The authors call the differences modest.

### Does IBS get worse around your period?

Often, yes. NIDDK says women with IBS often have more symptoms during their periods, and a review of 13 studies found more IBS symptoms during menses.

### Can IBS cause pelvic pain?

The NHS lists pelvic pain among other IBS symptoms. Because endometriosis and other gynecologic conditions can look similar, ongoing pelvic pain is worth a doctor’s visit.

### Is Gutli available?

See the official app page for current availability and pricing.

## Our pick: Gutli, meals and symptoms on one timeline

Once a doctor has ruled out other causes, the next question is what sets your symptoms off. Gutli logs meals with portions and check-ins for pain, bloating, nausea, energy and bowel movements with the Bristol Stool Chart, then shows them together on a timeline and calendar. Weekly and monthly summaries and a PDF or CSV report are ready for your appointment. It records and shows patterns; it does not diagnose.

- Meals and symptom check-ins on one timeline
- Bristol Stool Chart for bowel check-ins
- PDF or CSV report for your clinician
