Abstract: BACKGROUND: The view of insulin-requiring diabetes mellitus (IRDM) as an absolute contraindication for scuba diving has softened within the last 15 years. While a growing number of groups allow some individuals with IRDM to dive, studies of the plasma glucose (PG) response to diving are limited. Extremely few data exist for the teenage diver, despite strong interest of and in this group. We report the PG response to recreational diving in teenage novice divers with IRDM. METHODS: Seven divers (4F/3MF) participated in this observational study during a tropical diving camp. Mean age was 16.1+/-0.4 (16-17) years (mean+/-SD [range]). All had at least moderate recent PG control, documented by HbA1c levels of 7.3+/-1.1 (5.3-8.5)percent. PG values were recorded at 60, 30 and 10 min pre-dive and immediately post-dive for 42 dives. Data loggers recorded time/depth profiles. PG differences were assessed with ANOVA (significance at p less than 0.05). RESULTS: Maximum depth (49+/-25 fsw) and underwater time (39+/-17 min) were generally modest. Pre-dive PG exceeded 300 mg?dL-1 in 22percent of cases. Males had significantly higher immediately pre-dive PG levels (277+/-100 vs. 230+/-52 mg?dL-1, respectively) and greater immediately pre-dive to post-dive changes (-78+/-79 vs. -9+/-77 mg?dL-1, respectively). Males and females had similar post-dive PG levels (199+/-129 and 220+/-90 mg?dL-1, respectively). Post-dive PG was less than 70 mg?dL-1 in only one case (male: 61 mg?dL-1). CONCLUSIONS: While large plasma glucose swings from pre-dive to post-dive were noted, particularly in males, no symptoms or complications related to PG were reported. These data indicate that teenage divers with at least moderate control of IRDM can avoid hypoglycemia during uncomplicated, no-decompression recreational dives under benign environmental conditions. The impact of voluntary elevation of PG to protect against hypoglycemia during diving remains to be determined.
