Postprandial hypotension (PPH) occurs frequently and is thought to reflect an inadequate increase in cardiac output to compensate for the rise in splanchnic blood flow after a meal. Gastric distension by water attenuates the postprandial fall in blood pressure (BP). Cardiac hemodynamics (stroke volume (SV), cardiac output (CO), and global longitudinal strain (GLS)) have hitherto not been measured in PPH We sought to determine the comparative effects of water and glucose drinks on cardiac hemodynamics in healthy older subjects and individuals with PPH Eight healthy older subjects (age 71...

BACKGROUND: It is commonly known that headaches are induced by intake of specific food, drink, and/or additive. In addition, some patients experience postprandial headache independent of ingestion of specific items. Currently, information on the pathophysiology underlying this particular type of headache is scarce. CASE REPORTS: We report two cases in which headaches were observed after each meal. Postprandial hypotension was demonstrated in both cases. Tonometry-based continuous blood pressure measurement during head-up tilt revealed sympathetic dysfunction...

PURPOSE: Postprandial hypotension (PPH) has been associated with increased risk of syncope, falls, stroke, angina and mortality. As the majority of patients with PPH are asymptomatic, the diagnosis is often overlooked. The aim of this study was to perform a systematic review and meta-analysis of available scientific evidence on the likelihood of PPH in neurological diseases. METHODS: A systematic review of the literature (PubMed library, Cochrane Database for Systematic Reviews and Cochrane Central Register of Controlled Trials for results up to January 2017) identified 327 studies, of which 11 reported the frequency of PPH in patients with neurological diseases compared to healthy controls...

Allowing dialysis patients to eat during the treatment is controversial. It is, therefore, no surprise that practices and policies with respect to intradialytic food consumption vary considerably from unit to unit and from country to country. Those who defend the position of feeding during dialysis reason that intradialytic meals offer a supervised and effective therapy for protein-energy wasting. Those who take the opposite view argue that intradialytic food intake should be avoided for the following three reasons...

Nutrient ingestion induces a substantial increase in mesenteric blood flow. In older persons (aged ≥ 65 years), particularly those with chronic medical conditions, the cardiovascular compensatory response may be inadequate to maintain systemic blood pressure during mesenteric blood pooling, leading to postprandial hypotension. In older ambulatory persons, postprandial hypotension is an important pathophysiological condition associated with an increased propensity for syncope, falls, coronary vascular events, stroke and death...

: Postprandial hypotension (PPH) is a common condition that occurs primarily in elderly patients with type 2 diabetes mellitus (T2DM). This study aimed to assess the effectiveness of acarbose for PPH; it also investigated possible mechanisms behind PPH development. This single-blind, randomized controlled trial included 91 elderly patients with T2DM, aged between 60 and 80 years, who were inpatients at Beijing Hospital between March 2012 and November 2014. The patients were included into one of three groups: Group A, patients with T2DM without PPH; Group B, patients with T2DM with PPH receiving placebo; and Group C, patients with T2DM with PPH receiving acarbose...

BACKGROUND Postprandial hypotension, induced by an absorption of glucose from intestine, could be treated by acarbose; however, it was unclear whether dipeptidyl peptidase-4 inhibitor reduced postprandial hypotension. CASE REPORT A 78-year-old woman who had experienced episodes of dizziness and hypotension after eating was admitted to our hospital. During 24-hour ambulatory blood pressure monitoring, there were repeated episodes of marked postprandial hypotension; i.e., a significant systolic blood pressure reduction within two hours after eating (from -58 to -64 mm Hg after meals)...

Cervical and high thoracic spinal cord injury (SCI) drastically impairs autonomic nervous system function. Individuals with SCI at thoracic spinal level 5 (T5) or higher often present cardiovascular disorders that include resting systemic arterial hypotension. Gastrointestinal (GI) tissues are critically dependent upon adequate blood flow and even brief periods of visceral hypoxia triggers GI dysmotility. The aim of this study was to test the hypothesis that T3-SCI induces visceral hypoperfusion, diminished postprandial vascular reflexes, and concomitant visceral inflammation...

One-third of community-dwelling people older than 65 years of age fall each year, and half of them fall at least twice a year. Older care home residents are approximately three times more likely to fall when compared to community-dwelling older people. Risk indicators for falls are related to the older people's body, environment, behavior, and activities. An important health risk indicator is (orthostatic or postprandial) hypotension, which may induce cerebral hypoperfusion. Although the majority of falls remain without major consequences, 10% to 25% of falls in care homes result in bodily trauma...

Small, frequent meals (SFMs) are a dietary regimen characterized by multiple small eating episodes throughout the day. Clinical nutrition guidelines recommend SFMs (eg, 6-10 meals) to patients experiencing common symptoms (eg, early satiety) and gastrointestinal-related symptoms. However, whether the provision of SFMs palliatively improves morbidity of nutritionally at-risk individuals has yet to be elucidated. This narrative review summarizes current clinical guidelines recommending SFMs for the management of diseases in adult patients (≥18 years), with supporting experimental and epidemiologic evidence, and it provides suggestions pertaining to this recommendation by drawing on potential considerations from investigations in healthy adults...

Neurocardiovascular instability (NCVI) refers to abnormal neural control of the cardiovascular system affecting blood pressure and heart rate behavior. Autonomic dysfunction and impaired cerebral autoregulation in aging contribute to this phenomenon characterized by hypotension and bradyarrhythmia. Ultimately, this increases the risk of falls and syncope in older people. NCVI is common in patients with neurodegenerative disorders including dementia. This review discusses the various syndromes that characterize NCVI icluding hypotension, carotid sinus hypersensitivity, postprandial hypotension and vasovagal syncope and how they may contribute to the aetiology of cognitive decline...

Hypertension is very common in elderly subjects with type 2 diabetes. The coexistence of hypertension and diabetes can be devastating to the cardiovascular system, and in these patients, tight blood pressure (BP) control is particularly beneficial. Little information is available regarding the target BP levels in elderly hypertensive patients with type 2 diabetes, and therefore extrapolation from data in the general population should be done. However, it is difficult to extrapolate from the general population to these frail individuals, who usually have isolated systolic hypertension, comorbidities, organ damage, cardiovascular disease, and renal failure and have a high rate of orthostatic and postprandial hypotension...

Postprandial hypotension is one of the most important autonomic disorders in Parkinson's disease. However, its predictors remain unclear. We investigated which variable(s) predict the presence of postprandial hypotension in elderly patients with Parkinson's disease. The subjects were 64 patients with de novo Parkinson's disease who were 70 years or older. Postprandial hypotension was evaluated on a 75-g oral glucose tolerance test. Olfactory function, constipation, cardiac sympathetic or parasympathetic denervation, orthostatic intolerance on head-up tilt table testing, and other baseline characteristics were evaluated...

Both hypertension and orthostatic hypotension (OH) are strongly age-associated and are common management problems in older people. However, unlike hypertension, management of OH has unique challenges with few well-established treatments. Not infrequently, they both coexist, further compounding the management. This review provides comprehensive information on OH, including pathophysiology, diagnostic workup and treatment, with a view to provide a practical guide to its management. Special references are made to patients with supine hypertension and postprandial hypotension and older hypertensive patients...

Orthostatic hypotension (OH) is defined as a sustained pathological reduction in blood pressure within 3 min after orthostatic stress such as tilt-table testing or active standing. Non-neurogenic OH is caused by either decreased cardiac output or impaired vasoconstriction without a primary autonomic disorder whereas neurogenic OH results from inadequate release of norepinephrine in the vasomotor sympathetic system. Once non-neurogenic causes of OH such as medications and cardiac problems are ruled out, neurogenic OH can be considered...

Postprandial hypotension (PPH), a fall in systolic blood pressure (SBP) within 2 h of a meal, may detrimentally affect gait parameters and increase the falls risk in older people. We aimed to determine the effects of postprandial SBP on heart rate (HR), gait speed, and stride length, double-support time and swing time variability in older subjects with and without PPH. Twenty-nine subjects were studied on three days: glucose ("G"), water and walk ("WW"), glucose and walk ("GW"). Subjects consumed a glucose drink on "G" and "GW" and water on "WW"...
