- Fatigue
The outcomes were frequency of IDH episodes and number of nursing interventions during HD sessions, pre- and post-dialysis BP, subjective change in fatigue as measured by the Visual Analogue Scale (VAS), and recovery time from fatigue after dialysis at [ncbi.nlm.nih.gov]
Even mild dehydration (a loss of as little as 1 percent to 2 percent of body weight) can cause weakness, dizziness and fatigue. [heart.org]
Low blood pressure can make you feel tired all the time Highlights Low blood pressure can make you fatigued Drinking water can help you normalise your blood pressure Healthy changes in diet can help you beat low blood pressure Low blood pressure is also [ndtv.com]
- Sepsis
Importance: The effect of an early resuscitation protocol on sepsis outcomes in developing countries remains unknown. [ncbi.nlm.nih.gov]
Longer hypotension time with the thresholds of 65 and 70mm Hg was significantly associated with the risk of stage-3 progression in patients without sepsis, whereas the association was weak and not significant in patients with sepsis. [mendeley.com]
Septic shock – early sepsis usually presents with warm extremities and bounding pulses. Late sepsis will reveal cool, pale cyanotic extremities with mottling. 5. [cancertherapyadvisor.com]
However, sepsis may also occur. Sepsis occurs when these local bacteria spread to other parts of the body or systemic reaction occurs diffusely in the body, resulting in a systemic inflammatory response. [apollomd.com]
- Unconsciousness
Tell your family members to call an ambulance if you become unconscious. Ask them to learn CPR. Follow-up care Make a follow-up appointment as directed. [fairview.org]
If low blood pressure causes a person to pass out (become unconscious), seek treatment right away. Or, call the local emergency number such as 911. If the person is not breathing or has no pulse, begin CPR. [nlm.nih.gov]
The most dramatic symptom of sudden hypotension is unconsciousness. Usually, low blood pressure develops over time. [betterhealth.vic.gov.au]
- Pallor
6 Tips to Prevent a Heart Attack The most common symptoms of hypotension are: Dizziness, blurred vision, vertigo Nausea and vomiting Pallor Chest pain Fainting Difficulty breathing Headaches Numbness in legs or hands A feeling of instability A stiff neck [steptohealth.com]

Particularly in sub-Saharan Africa with its paucity of renal replacement therapy options to manage kidney failure, every effort to limit AKI, SORO-ESRD and exacerbation of kidney dysfunction in general, must be vigorously applied. [ncbi.nlm.nih.gov]
When blood pressure is low, your organs do not receive enough blood which can even cause strokes, heart attacks or kidney failure if left uncontrolled. There are several signs and symptoms your body may experience. [ndtv.com]
Moderate dehydration may cause orthostatic hypotension, and severe dehydration (hypovolemia) can lead to shock, kidney failure, confusion, acidosis, coma, and even death. [uspharmacist.com]
Prolonged and severe dehydration can lead to shock, kidney failure, confusion, acidosis (too much acid in the blood), coma, and even death. [medicinenet.com]
High blood pressure can lead to serious conditions such as stroke, coronary heart disease and kidney failure. The lower your blood pressure, the less likely you are to suffer from these problems. [bupa.co.uk]

Treatment
CONCLUSION: Greater occipital nerve treatment may have a role in management of SIHH. © 2017 American Headache Society. KEYWORDS: greater occipital nerve block; pulsed radiofrequency treatment; spontaneous intracranial hypotension headache [ncbi.nlm.nih.gov]
Prognosis
It occurs in susceptible patients, on average 1-5 days after the IH trigger, and seems clinically and radiologically similar to more common hypertensive cases in terms of initial presentation and prognosis. [ncbi.nlm.nih.gov]
Prognosis Although an increased mortality rate in hypopituitary patients is well documented, the actual cause of the increased mortality is not clear. If relevant hormones are adequately replaced, prognosis in hypopituitarism is good. [patient.info]
Prognosis Low blood pressure as a result of injury or other underlying condition can usually be successfully treated if the trauma is not too extensive or is treated in time. [medical-dictionary.thefreedictionary.com]
Etiology
FOLLOW UP: If a reversible etiology is identified, orthostatic blood pressure and pulse should be repeated once the etiology is corrected to assure improvement and that multiple etiologies were not contributing factors. [consultgeri.org]
A number of etiologies for spinal CSF leaks have been identified, including the recent discovery of CSF-venous fistulas, and these various etiologies may require different diagnostic and therapeutic pathways in order to affect a cure. [ncbi.nlm.nih.gov]

In terms of epidemiology, septic shock is by far and away the most common. In a trial of over 1600 patients with shock, 62% had septic shock, 16% had hypovolemic shock, and 16% had cardiogenic shock. [accessmedicine.mhmedical.com]
Summary Epidemiology It has been described in three families. [orpha.net]
Pathophysiology
Currently, information on the pathophysiology underlying this particular type of headache is scarce. We report two cases in which headaches were observed after each meal. Postprandial hypotension was demonstrated in both cases. [ncbi.nlm.nih.gov]
The pathophysiology of IOH is thought to be a temporal mismatch between cardiac output and vascular resistance. [clinsci.org]
