We say does bariatric surgery can affect memory depending on the situation. When the body doesn’t get enough vitamin B1 or thiamine, it causes Wernicke’s encephalopathy, which affects the brain and nervous system. It can also lead to vision issues like rapid eye movements.
The syndrome is most common in people who ejaculate frequently after surgery, according to the study. It usually happens one to three months after surgery, though in one case it happened 18 months later.
The researchers looked through the scientific literature for any cases of the syndrome that had occurred after bariatric surgery. There has been a total of 32 cases reported.
Seizures, hearing problems, psychotic disorders, muscle weakness, and pain or numbness in the feet or hands were common neurological symptoms not particular to Wernicke’s encephalopathy.
If you or someone you know has had weight loss surgery and is experiencing any of these symptoms, you should see a doctor right away.
When doctors see patients with neurological complications after weight loss surgery, they should consider vitamin B1 defect and Wernicke’s encephalopathy. The prognosis is usually favourable if treated promptly.
Vitamin B1 is given to patients via IV or injection as a treatment. Thirteen of the 32 people have fully recovered. Many people continued to have memory issues, weakness, or trouble coordinating their movements.

After Surgery for Your Brain
It backs controversial new guidelines that say doctors should only consider gastric bypass surgery for the large percentage of diabetics with a BMI of 30 or higher, and only for those with a BMI of 40 or higher.
According to studies, people who lose weight through diet and exercise lose more weight, keep it off longer, and have better blood sugar as those who lose weight through other means. A new mouse study suggests that bariatric surgery’s effectiveness may be due in part to the changes it causes in the brain.
Hyperactivation of a neuro pathway leading to the lateral parabrachial nucleus, a midbrain area that receives sensory input from stomach-sensing neurons in the brainstem, is caused by gastric bypass surgery. The amygdala, the visual cortex emotion and fear processing centre, then to the body.
Obese mice had Roux en Y bypass surgery, in which the majority of the stomach was removed, and a small pouch attached only to the small intestine was left. Mice show increased activation of this neural pathway, smaller meal sizes, and a preference for less fatty food shortly after surgery.
They start to secrete more satiety hormones as well. Humans show similar behavioural and hormonal changes after bypass surgery, implying that physiological changes are similar as well. However, the authors say it’s difficult to look at this circuit in humans with brain imaging so because solution isn’t task dependent.
The sudden change contact of gastric contents with the small intestine, rather than the pre-digested mixture that usually comes from the stomach, is likely to be the cause of the change in brain activity. These patients must essentially relearn how to eat.
They had grown accustomed to the large parts and had placed the food on the table. It was a pleasurable experience for them. It hurts them if they do this after surgery. This new bad publicity, which is a wonderful thing, is likely to be reflected in brain regions deemed hyperactive by surgery.
It shows that in mice, the pathway is no longer overactive after a few weeks, possibly because the brain was indeed recruiting other processes to encourage them to eat less. He goes on to say that this path is most likely only a small part of the puzzle.
Bariatric surgery has been shown to affect the reward center, making fatty foods less pleasant. One unanswered question is why gastric bypass does not result in the frustratingly slow digestion seen in people who lose a lot of weight by changing their lifestyle.
How Does Bariatric Surgery Affect the Brain?
The results of a new study have been published in the journal Experimental Brain Research, which highlights the positive effects of gastric bypass surgery on the brain.
The study shows that the procedure affects the development of a pathway from the brain stem to the amygdala, which is the emotional processing center of the brain. This means that the brain is able to process a higher amount of sensory information if the patient’s stomach size is reduced.
The study compared bariatric surgery candidates with healthy controls. Cognitive function was assessed at two weeks after surgery and 14 weeks later. The participants were evaluated before and after surgery to assess any effects.
During each assessment, young reference controls were evaluated and the range of normal values for each outcome measure was determined. CVR to hypercapnia (5% CO2), MCA vasodilation, and cognitive function were assessed using validated neurocognitive software.
Despite the positive findings, the results suggest that there may be other factors influencing brain changes after bariatric surgery. Functional connectivity of the reward and default mode networks, and whole-brain connectivity are all impacted differently by the procedure.
However, one study found that the effects of surgery on the reward network were associated with a lower BMI and increased average head motion. These findings are still preliminary. Further research should investigate whether DMN connectivity is affected by bariatric surgery.
This study involved a randomized, controlled study in which CO2-inhalation induced a decrease in MCA CSA, although the results did not differ statistically from age-matched controls.
In addition, the researchers noted that vasoconstriction in obese bariatric surgery patients during CO2 challenges is associated with lower NO bioavailability. It is also possible that differences in MCA BOLD imaging are related to regional variations in cerebral vascular health.
