This topic is about understanding why people with ostomies might experience sudden weakness, dizziness, and extreme fatigue. The discussion explores whether these symptoms could be linked to low blood sugar or food moving too quickly through the bowel. Here are some insights and advice shared on the topic:

1. Dehydration is a significant concern:
- People with ileostomies lose more fluids, and even a single day of low fluid intake can lead to fainting, visual disturbances, sweating, hot/cold shivers, and seizures for those who are susceptible.
- It's important to always carry water and sip it throughout the day.

2. Salt (sodium) depletion can happen quickly after ileostomy output:
- Signs include craving salt, a swollen tongue, and persistent thirst.
- Increasing dietary salt through salt tablets, salty snacks, or crisps/chips can quickly restore dangerously low sodium levels.
- Low sodium levels can mimic or coexist with low blood sugar symptoms and may cause mental confusion.

3. Blood-glucose drops, especially in diabetics, can cause shakiness, disorientation, and weakness, potentially leading to a coma if untreated:
- It's important to treat with fast-acting sugar followed by a longer-acting carbohydrate.
- Monitoring blood-glucose levels is crucial if you have diabetes or long gaps between meals.

4. Comprehensive blood tests are essential:
- It's important to check electrolytes, glucose, iron, B-vitamins, and liver function to rule out multiple overlapping deficiencies.

5. Similar symptom patterns have been reported by other ostomates:
- Symptoms include passing out with convulsions, a constant need for water, salt cravings, and low iron.
- Severe sweating, cold shivers, nausea, clumsiness, and falls have been noted, even with normal blood-glucose readings.

6. Consider discussing alternative or additional diagnoses with a doctor:
- Meniere’s disease, which can cause dizziness, nausea, and falls.
- Fibromyalgia or ME/CFS, which can lead to extreme fatigue, "brain fog," pain, and intermittent symptoms.
