Fasting means abstinence from drinking any liquids, eating, smoking and taking anything parenterally.  It is intermittent in nature from the start of dawn to end at dusk. Fasting has various physiological effects on different biological parameters of the human body. Previous studies that look at effect of Ramadan fasting on blood pressure have focused mainly on hypertensive patients and patients with already established heart disease.(1,2)There is very limited data regarding the effect of fasting on the normal population. (3,4) A few previous studies have advocated a hypotensive role of fasting.(5) In our study published in Journal of Ayub Medical College Abbottabad (JAMC) in 2015, “Effects of Ramadan Fasting on Blood pressure in normotensive males”, we investigated the effect of Ramadan fasting on blood pressure of normotensive men. We conducted a repeated measure observational study in Karachi, Pakistan on 70 individuals who were normotensive, non-smokers between the ages of 18–50 years. . Blood pressure, pulse, BMI of each participant was recorded one week before the start of Ramadan and in the first, second and third week of Ramadan. The results of our study show that intermittent fasting has a hypotensive effect in normotensive males as proven in animal models and certain human population. There was an average drop of 8/3 mmHg and while the results are significant, their clinical relevance needs to be analysed. Studies on animal models have suggested atrial natriuretic peptide, catecholamines, opiates and body mass index as possible reasons for the decrease in blood pressure due to fasting.(3, 6)  Dewanti et al suggested that the cause of drop in blood pressure was the drop in BMI however in our study we found that a drop in BMI only occurred before Iftar towards the end of the fast. There was no significant drop in post-Iftar BMI although there was a significant drop in blood pressure post-Iftar. At the same time ANP has been investigated and found to have no relationship with the phenomenon. We observed a drop in both pre and post Iftar period blood pressure readings. From the community health perspective these results cast doubt on the results of screening for hypertension in the month of Ramadan. Our study has some limitations. First of all, our results cannot be generalized to women and individuals suffering from chronic diseases. Secondly, one cannot exclude the confounding effect of the type of food taken during the breaking of the fast for example individuals taking stimulants like coffee and tea might have yielded readings that were confounded.","PeriodicalId":90593,"journal":{"name":"Journal of fasting and health","volume":"4 1","pages":"75-76"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68366458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They have an inherent osmotic diuretic effect and lead to some volume loss and possible dehydration. There is some concern about the safety of using SGLT2 inhibitors in Muslim type 2 diabetes mellitus (T2DM) patients during the fast during Ramadan. Currently, there is a dearth of research data to help guide physicians and reassure patients. One study confirmed good glycemic control with less risk of hypoglycemia and no marked volume depletion. Data in the elderly and in combination with diuretics are reassuring of their safe to use in Ramadan in general. SGLT2 inhibitor-related diabetic ketoacidosis has not been reported during Ramadan and is unlikely to be relevant. Survey of physicians revealed that the majority felt that SGLT2 inhibitors are generally safe in T2DM patients during Ramadan fasting but should be discontinued in certain high risk patients. Some professional groups with interest in diabetes and Ramadan fasting included SGLT2 inhibitors in their guidelines on management of diabetes during Ramadan. They acknowledged the lack of trial data, recommended caution in high risk groups, advised regular monitoring and emphasized pre-Ramadan patients’ education. In conclusion, currently, knowledge, data and experience with SGLT2 inhibitors in Ramadan are limited. Nonetheless, stable patients with normal kidney function and low risk of dehydration may safely use the SGLT2 inhibitors therapy. Higher risk patients should be observed carefully and managed on individual basis.","PeriodicalId":90593,"journal":{"name":"Journal of fasting and health","volume":"4 1","pages":"82-87"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68365676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hyperthyroid patients receiving treatment with methimazole or carbimazole have to adjust to 1-2 daily doses, while patients using propylthiouracil need to change their drug regimen. Severely symptomatic hyperthyroid patients require immediate treatment and must avoid fasting for a few days.

Prolonged fasting increase gastric acid and pepsin levels, which promote the risk of duodenal ulcer perforation (DUP). Effects of Ramadan fasting on DUP have not been thoroughly studied yet, and the limited number of studies investigating the impact of Ramadan fasting on DUP yielded discrepant results. This study aimed to evaluate DUP frequency during Ramadan 2011-2015 and compare it with other months. Methods: This cross-sectional study was performed in 82 patients undergoing surgery due to DUP during July 2011-September 2015. The demographics, history of addiction, use of nonsteroidal and antiinflammatory drugs, previous history of acid peptic disease, as well as complications and outcomes of treatment were recorded and analyzed, and the obtained results were compared between Ramadan and other lunar months. Results: The majority of patients were male (86.6%, 71 patients), with a mean age of 43.9±16.5 years (age range: 20-75 years). Male to female ratio was 6:1. Cases with less than 30 years of age were less frequent (22%, 18 patients). DUP was more frequent during Rajab with nine cases (11%), while during Ramadan, six cases were reported, the difference between Ramadan and other months regarding the incidence of DUP was not significant (P=0.7). Risk factors such as smoking (60%) and addiction (44%; especially to crystal and crack) were noted. Consumption of nonsteroidal antiinflammatory drugs in 20 (24%) patients, and use of antacids in 17 (25%) patients. Distribution of DUP in different blood types was as follows: O+=41%, A+=28%, B+=23%, AB=5%, and O-=3%; moreover, post-operative Helicobacter pylori antibody was present in 67% of the patients. Conclusion: Ramadan fasting did not escalate DUP incidence, and those with DUP risk factors can fast with the use of antacids.","PeriodicalId":90593,"journal":{"name":"Journal of fasting and health","volume":"10 11 1","pages":"25-31"},"PeriodicalIF":0.0,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68365683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this review article, we aimed to discuss the possible effects of fasting and regular physical activity on risk factors for cardiovascular diseases.  Methods: Online databases including Google Scholar, SID, PubMed, and MagIran were searched, using the following keywords:  “training”, “exercise”, “physical activity”, “fasting”, “Ramadan”, “metabolic syndrome”, “fat percentage”, “blood pressure”, “blood sugar”, “cholesterol”, “triglyceride”, and “lowdensity lipoprotein-cholesterol”. All articles including research studies, review articles, descriptive and analytical studies, and ross-sectional research, published during 2006-2015, were reviewed. In case of any errors in the methodologyof articles, they were removed from our analysis. Results:Based on our literature review, inconsistent findings have been reported on risk factors formetabolic syndrome. However, the majority of conducted studies have suggested the positive effects offasting on reducing the risk factors for metabolic syndrome. Conclusion: Although fasting in different seasons of the year has no significant impacts on mental health or physical fitness, it can reduce the risk of various diseases such as cardiovascular diseases. Also, based on the conducted studies, if individuals adhere to a proper diet, avoid excessive eating, drink sufficient amounts of fluids, and keep a healthy level of physical activity, fasting can improve their physical health.","PeriodicalId":90593,"journal":{"name":"Journal of fasting and health","volume":"4 1","pages":"1-16"},"PeriodicalIF":0.0,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68365642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
