10 facts : What is SIBO or blind loop syndrome ?

1. SIBO, abbreviated as small intestinal bacterial overgrowth, is a condition where there is an overgrowth of bacteria that are not supposed to be present in the normal scenario in that part of the digestive tract. This occurs particularly following a disease or abdominal surgery, when the passage of food and waste becomes slower, creating a breeding ground for bacterial overgrowth.

2. When the wrong types of bacteria overgrow in the small intestine, they feed on the nutrients and food for the otherwise beneficial bacteria, which can lead to abnormal symptoms in gut health. These wrong types of bacteria can feed on the protein and vitamin B12, bile salts which are supposed to support the digestion of fats. In normal circumstances, the small intestinal bacteria digest the carbohydrate and convert it to short-chain fatty acids and gas. Therefore, when there is overgrowth of bacteria, more gas and toxins are produced in the gut leading to many GI symptoms and malnutrition in the long run.

3.The prevalence of SIBO is about 80-90% in cases of irritable bowel disorder, intestinal dysmotility , pancreatitis and chronic systemic conditions. It is more prevalent in the elderly and female population. Usually, the incidence increases with age and the presence of chronic intestinal disorders and dysmotility. SIBO is considered by clinicians as a differential diagnosis of other gastrointestinal non-specific disorders as the actual aetiology is still unknown.

4. The GI symptoms following SIBO are many:

• Gas, bloating, nausea

• Abdominal pain, distention

• Constipation

• Indigestion

• Weight loss, fatigue

• Watery or mucus in poop.

• Hard or lumpy poop.

5.Unexpected and systemic signs may appear due to excess toxins released in bloodstream

(endotoxemia) in SIBO:

• Food intolerence

• Fatty liver

• Fibromyalgia

• Irritable bowel syndrome

• Anxiety, depression, suicidal thoughts

• Endometriasis

• Disruption of mentrual cycle.

• Prostate diseases.

• Atrial fibrillation

• Siezure

6.Though the actual cause of SIBO is unknown, hence, there are several underlying conditions which can be the risk factors:

• Ageing: As age progresses, there may be changes in microflora, degeneration of acid-producing gastric cells, intestinal dysmotility which may lead to bacterial overgrowth.

• Irritable bowel syndrome leads to dysmotility, delayed transition of food, wastage.

• Chonic metabolic diseases like uncontrolled diabetes,

• Celiac disease,

• Lupus,

• Scleroderma,

• Pancreatitis,

• Chronic kidney diseases

• Fatty liver,

• Structural problems in the intestine due to gastric surgery, partial blockage, antibiotics or narcotic drugs overuse.

7. Several complications of SIBO can eventually worsen gut health if left untreated:

• Inadequate digestion and absorption of fat, protein, carbohydrate: Since, overgrowth of bacteria in the small intestine damages the bile salts so the fat remains undigested. The mucous lining of the intestines is damaged too by the excess bacteria causing poor absorption of carbohydrate, fat and protein. Therefore, there is malnutrition, diarrhoea, and weight loss.

• Vitamin B12 deficiency: As the fat remains undigested, the fat-soluble vitamins A, D, E, and K remain unabsorbed. Vitamin B12 which is synthesised in the small intestine is completely affected So, the individual may suffer from vitamin B12 deficiency. Therefore, due to B12 deficiency, nervous system functioning is affected, and blood cell production is lowered. There can be irreversible damage to the nervous system in the long run.

• Calcium absorption: Bacterial overgrowth damages the intestine slowly, resulting in poor absorption of calcium thereby affecting bone health. Weakened bones, prone to fractures, and osteoporosis are common. Kidney stones are also common in cases of poor calcium absorption.

8.There are no standard diagnostic tests for SIBO. The clinical symptoms of SIBO can be nonspecific. Usually, a carbohydrate breath test is considered which is inexpensive and non-invasive. A bacterial culture of jejunal aspirate of more than 1000 units/ml can support the diagnosis. Upper endoscopy is invasive but is done in patients to further support the diagnosis. Laboratory findings like vitamin levels, malnutrition markers are considered to support the diagnosis. Only, in rare cases is, biopsy of the small intestine done. Imaging tests like CT, MRI are done to rule out intestinal abnormalities.

9.Since the condition of SIBO is complex and can be involved with multiple underlying conditions, it is very difficult to manage and treat such cases. The treatment is mainly symptomatic like changing diet, lifestyle, and antibiotics to reduce the bacterial colonies. The recurrence of SIBO is also common so repeated courses of antibiotics are necessary. Supplementation of vitamins in certain cases is required. Surgery is only necessary in case of small intestinal abnormality, diverticula, bowel obstruction, or Crohn’s disease.

10.Again there is no standard diet for every individual who suffers from SIBO. It is individual-specific depending on symptoms and underlying conditions. The goal of diet change is to assist in the treatment and lower the symptoms. The diet should be low in carbohydrates, low in fat, and moderate to low in fibre. Processed sugar items, dairy, whole grains, deep-fried items, and raw vegetables should be avoided. Generally, probiotic-rich food, meat or fish, rice, cooked vegetables, plenty of fluid/water/soups and vitamin supplementation are recommended by the experts.

10 facts to know about Vitamin D linking to mental health🧠

Vitamin D deficiency is critical for both physical and mental health. Here are some facts to understand the impact of vitamin D on mental health.

1.Several research studies have concluded that low vitamin D levels are directly linked to anxiety, mood changes, depression and cognitive dysfunction such as impaired memory, sadness, weight loss and loss of appetite. Studies have not shown that vitamin D deficiency causes depression but people who suffer from depression do show low levels of vitamin D.

2. Vitamin D mainly maintains the body’s calcium homeostasis. It is also crucial as a neurosteroid hormone and plays a significant role in maintaining normal brain functions and helping in brain development. Therefore, numerous studies have shown that hypovitaminosis D is linked to depression and neurocognitive disorders.

3.Some studies have shown that seasonal affective disorder (SAD) is more prevalent in winter as there is a lowering of Vitamin D levels in the cold season. Lack of exposure to sunlight in winter months is shown to increase the incidences of depression, mood changes and anxiety issues.

4. Rising cases of suicide have been a common risk factor for low vitamin D levels (psychiatric times.com).A research study in 2023 found a correlation between low vitamin D levels with cases of suicidal behaviour. Therefore, vitamin D supplementation is mandatory for all those who have low levels can help to address mental health issues and prevent cases of suicide thereby saving lives.

5.As mentioned earlier, Vitamin D is required for normal brain development. Vitamin D supplementation is essential in childhood for overall brain and cognitive development. Low levels of vitamin D have been found in many cases of ADHD (attention deficit hyperactive disorder). Improved levels of vitamin D by supplementation have shown marked improvement in symptoms of ADHD children.

6. Vitamin D deficiency has been found to have a direct correlation with adult schizophrenia. Studies show that it is quite common to have in individuals with poor nutrition, elderly persons, people living in regions with insufficient sunlight, or during pregnancy. So, it is important to routinely check the levels of Vitamin D to reduce such risk factors. Correction of the levels of vitamin D shows marked improvements in symptoms of such mental illness.

7. Vitamin D acts as a neuroprotective neurotransmitter and helps to maintain the functions of neurons and glial cells of the central nervous system. So, administrating Vitamin D helps to reduce the oxidative stress and neurotoxicity on the cortical neurons. Therefore, controlling the neuronal inflammations helps to reduce many psychiatric illnesses.

8.Strong evidence shows that low levels of Vitamin D are related to neurodegenerative diseases like Alzheimer’s disease, dementia, and Parkinson’s disease. Vitamin D supplementation can improve or even prevent the neurodegenerative process by reducing the deposition of beta-amyloid plaques, intra-neuronal tangles of tau-protein and loss of cholinergic neurons and synapses.

9. Vitamin D levels ranging from 50nmol/L or above are sufficient to maintain overall physical and mental health well-being. Blood levels below 20 ng/mL are treated as insufficient and require immediate vitamin D administration. Normal levels can be maintained by exposure to sunlight, vitamin D supplementation and food sources like oily fishes, eggs, meat, liver, veggies like broccoli, pumpkin, green leafy veggies, green peas, avocados and many more.

10. Though vitamin D is not the only cause of mental health issues, essentially, it is an important nutrient to maintain normal brain function and neurochemistry. In the general population, many people do suffer from vitamin D deficiency, unknowingly. Supplementation of vitamin D can improve the blood levels in individuals and can at least help address the challenges of mental health issues.
