I'm wondering about Lundrgen's description of Reeva as "pre-menopausal" as a factor that may have slowed down the stomach-digestion phase.
She was under 30 and therefore not pre-menopausal in layman's terms, but I see from Googling it that the term is sometimes used in medical contexts to deisgnate the whole period from onset of menstruation to the menopause. But on that definition, is it really true that female stomach digestion is significantly delayed for the whole of the period of thirty to forty years in which they are "pre-menstrual"? Is it not rather that stomach digestion is only significantly slowed down in the much shorter period when fertility really tails off - a stage which Reeva had not yet reached?
CL may have misspoke?? But articles claim she stated "premenopausal"I know little about factors she described and how they affect gastric emptying. In a normal healthy individual at rest the composition of the meal ingested is primary determinant. Liquids faster than solids, carbohydrates quickly etc.
I did see that
peri-menopausal women may have delayed gastric emptying and post menopausal as well. Reeva was premenopausal, as you stated, so this shouldn't be a factor.
Cannot find anything yet that claims gastric emptying reliably varies during the various portions of the month in a normal premenopausal woman still cycling.

Nel should have called Roux and the witness on this one:
"Roux, up for re-examination, chose a mathematical path to rubbish Nel’s mathematical path. He pointed out that 200ml of food was still in Steenkamp’s stomach at 11am the next morning. If Saayman was correct and Steenkamp ate at 1am, then – using the 10% of total food measure – Steenkamp would have had to have eaten 5 litres of food at 1am. Roux’s point was that all this speculation can only ever be just that: speculation. Lundgren agreed."

Roux refers to 1 am to 11 am, which is not at all applicable.
The only time periods to be considered should be from 7pm - 3:05 am -DT contention or 1 am - 3:17 am PT contention.
Gastric emptying should effectively cease after death. I don't know if the pyloric sphincter relaxes like the anal sphincter and urethra do post mortem. I acnnot find anything that adresses post mortem emptying. Reeva was possibly in flight or fight mode near her death so GI motility in general would be minimal.
Although gastric "enzymes" could continue to work in theory, like a test tube under certain conditions, they are temperature and pH ependent. Short or continued digestion by enzymes would only change the 'consistency' of the gastric contents and not the volume of those contents.
Someone asked earlier about the volume. My understanding is that the pathologist measures the entire contents. Yes, part of the volume are secretions, acid, enzymes, etc. Ingested liquids empty much faster than solids. My best guess was hers was sludge like partially digested food with yet undigested vegetable matter containing secretions, enzymes and acid, all measured in toto.
Way behind, very much appreciate the many posts and mini transcripts.
