Hypoglycemic unawareness in diabetes -
HAAF is a type of functional sympathoadrenal failure caused most commonly by recent antecedent iatrogenic hypoglycemia and is at least partially reversible by careful avoidance of hypoglycemia.
HAAF can be maintained by recurrent iatrogenic hypoglycemia [ 32 ]. It is vital to distinguish HAAF from conventional autonomic neuropathy, which can also be caused by diabetes. Sympathoadrenal activation appears to be inhibited only in response to hypoglycemia, while autonomic activities in organs, such as the heart, gastrointestinal tract, and bladder, are unaffected [ 32 ].
Our case was examined for this possibility due to her long history of severe hypoglycemic attacks, which needed further evaluation to rule out having HAAF after an evaluation of sympathoadrenal response to hypoglycemia.
People with HU are unable to detect drops in their blood sugar level, so they are unaware that they require treatment. Unawareness of hypoglycemia increases the risk of severe low blood sugar reactions when they need someone to help them recover.
People who are unaware of their hypoglycemia are also less likely to be awakened from sleep when hypoglycemia occurs at night. People who are hypoglycemic but are unaware of it must take extra precautions to monitor their blood sugar levels regularly.
This is especially true before and during critical tasks, such as driving. When blood sugar levels are low or begin to fall, a CGM can sound an alarm. Such a device can be a great assistance to people with HU [ 12 , 15 ]. With continuous BG monitoring, children and adults with T1DM spend less time in hypoglycemia and simultaneously decrease their HbA1c level [ 33 , 34 ].
A prior study showed that diabetic patients with reduced beta-adrenergic sensitivity may be unaware of hypoglycemia, and the best suggestion for these patients is to strictly avoid hypoglycemia [ 35 , 36 ].
Our patient was also advised to have emergency glucose tablets, intermuscular, or intranasal glucagon injections at her disposal all of the time to avoid hypoglycemic attacks. The glucagon injection pen was not available in Iran at the time of the episode described here, neither was a CGM, so she was recommended to follow educational sessions on carbohydrate counting and perform excessive SBGM.
The patient was given strict advice based on her job and profession, as well as the need to control her blood sugar level to the extent that it did not interfere with her professional and daily functioning [ 12 ].
She was advised to see her endocrinologist to adjust her insulin dose based on her unawareness of hypoglycemia attacks and her work schedule, which may not allow her enough time to rest and consume enough carbohydrates, potentially leading to life-threatening attacks, especially since her coworkers were unaware of her medical condition.
It is strongly advised that people with diabetes, especially patients like this case, wear some sort of identification, such as a bracelet, or carry a card that state their condition [ 15 ].
Normalization of autonomic response takes 7—14 days on average, but it can take up to 3 months to normalize the threshold of symptoms, neuroendocrine response, and glucagon response although glucagon response is never fully recovered [ 37 , 38 ].
Another suggestion was to switch human insulin to the analog type of insulin. Hypoglycemia is a fairly common complication in diabetic patients receiving oral or insulin therapy.
However, in a subset of patients who are unaware of hypoglycemia for a variety of reasons, these warning signs do not exist, resulting in severe and life-threatening hypoglycemic episodes.
As a result, patients who have multiple episodes of HU are advised to raise their blood sugar control threshold for at least 2 weeks and to wear at all times a bracelet or label indicating their medical condition. In addition, in these patients, the use of CGM equipped with alarms in the occurrence of severely low blood sugar can be a perfect option.

Background: Hypoglycemic unawareness in diabetes unawareness Hypoglycemic unawareness in diabetes is associated with significant Energy drinks for late nights. Screening for impaired awareness Hypglycemic hypoglycemia unawareeness patients with diabetes is important to minimize those risks. There are limited data on the Unawarenesw of HU in patients with diabetes in Saudi Arabia KSA. In the current study, we investigated the frequency of HU and its risk factors among insulin treated diabetic patients in Madinah, KSA. Methods: A cross-sectional study was conducted in a diabetes center and four primary healthcare centers at Madinha, KSA. The risk factors for HU were determined. Results: Of the included patients, Hypoglycemia unawareness is more common Hypoglycwmic previously thought and can lead to Hypoglycemic unawareness in diabetes complications. Unawarebess All-natural caffeine pills, Flaxseeds in paleo diets All-natural caffeine pills impaired awareness diiabetes hypoglycemia, was considered a unaawareness mostly inawareness in people with type 1 diabetes. But with the increased use of continuous glucose monitors CGMsit is now evident that hypoglycemia unawareness also affects many people with type 2 diabetes who use insulin or other medicines that can cause hypoglycemia. The CDC reports that in1. Elizabeth Seaquist, MD, is a professor of medicine at the University of Minnesota. As an expert in hypoglycemia unawareness, she shares her insights on managing this complication.
