SIBO: Internal Contribution to Dysfunction

Small Intestinal Bacterial Overgrowth (SIBO) is commonly defined as an increased number of bacteria and/or abnormal type of bacteria in the small intestine (Kwiatkowski, et al., 2017).  SIBO plays a role in malabsorption and nutritional deficiencies, altering the body’s homeostatic state (Zeigler & Cole, 2007). The build-up of displaced bacteria can cause an increase in intestinal permeability leading to general malabsorption and alterations of certain water-soluble B vitamins including biotin, folate and B12 (Bures et. al., 2010). Overconsumption of vitamin B12 by the dysbiotic anaerobic flora, can cause deficiency and lead to conditions such as megaloblastic anemia or polyneuropathy (Sachdev & Pimentel, 2013).  Bacterial overgrowth leads to deconjugation of bile salts which appears to irritate the mucosal lining of the intestine and cause malabsorption of fatty acids (Wanitschke & Ammon, 1978). Metabolic absorption of nutrients by dependent organs and bodily systems may be affected, due to altered health of the small intestine.  A recent study found that Non-alcoholic fatty liver disease, which affects 16-30% of the general population, was significantly higher in patients with SIBO compared to patients without SIBO (Fialho et al., 2016).  Dysbiosis of the gut bacteria has also been linked to other autoimmune diseases such as rheumatoid arthritis, type 1 diabetes and asthma (Tremlett et al., 2016). The symptoms of SIBO can have a significant impact on quality of life. The condition can be economically burdensome as patients are likely to spend substantial sums of money on physician visits and medications seeking relief from their symptoms (Yakoob et al., 2011).  Socially, patients may suffer from gastrointestinal (GI)-specific anxiety (GSA) characterized by being fearful of GI symptoms, such as abdominal pain or discomfort, gas, and altered bowel habits. The unpredictability of their condition can lead to self-seclusion and avoidance of public and social gatherings (Lackner et al., 2014). As evidenced by the research presented above, SIBO affects the gastrointestinal and supporting systems in a variety of ways, placing a heavy burden on individuals affected.  Curious about the contribution of STRESS to SIBO (and other digestive dysfunctions)?

A Wide-Eyed Approach to Caffeine

Caffeine is often found in analgesics because it lowers gastric pH, increases antinociceptive effects, drug absorption and gastric motility, and improves mood and reaction time (Lipton et al., 2017). It works to mitigate pain by activating the pain-suppressing noradenosine pathway and acting as a nonselective antagonist of adenosine A1, A2A and A2B receptors which speeds nerve cell communication and results in vasoconstriction (Lipton et al. 2017, Chen et al., 2018). Caffeine is an adenosine receptor antagonist and blocks the detection of pain by blocking adenosine receptors and inhibiting phosphodiesterases (Mantegazza et al., 1984). Caffeine absorbs rapidly and has a half-life of 3–6 hours. This can cause consumers to become dependent on its stimulating effects. Overconsumption of caffeinated soda in adolescents has been associated with caffeine-induced headache. Adolescents consuming 200mg caffeine daily presented with daily headaches until soda intake was gradually discontinued over a two-week period (Hering-Hanit, R. & Gadoth, N., 2003). According to Juliano, et al. (2012), the mechanism of caffeine-withdrawal headache is believed to be an “increased functional sensitivity to endogenous adenosine via the upregulation of adenosine receptors.” In this study, participants consuming >100mg caffeine per day reported significantly higher incidence of headaches during caffeine abstinence (Juliano, L., et al., 2012). Caffeine consumption has also been linked to side effects such as hypoglycemia and difficulty sleeping. In one study, caffeine triggered a decrease in middle cerebral artery velocity, and increased epinephrine. Participants reported feeling hypoglycemic marked by trembling, weakness, facial flushing and palpitations. Norepinephrine, growth hormone, and cortisol also increased as a result of caffeine intake (Kerr et al., 1993). Another study found that caffeine ingestion near bedtime affected individuals’ sleep regarding later bedtime, sleep duration, and fragmentation (Clark & Landolt, 2017).    Not all side effects of caffeine are negative. Caffeine has been associated with improved mental performance on cognitive tasks and decreased cognitive decline with aging. It has also been shown that caffeine consumption in mid-life may reduce Alzheimer’s disease by up to 65% (Arendash & Cao, 2010).   References: Arendash, G. W., & Cao, C. (2010).
