Glucagon-Like Peptide

Glucagon-Like Peptide Portugal

Glucagon-Like Peptide 1

What is Glucagon-Like Peptide 1 (GLP1), and how does it influence weight and cognition?

Scientists believe glucagon-like peptide 1 (GLP-1) aids insulin secretion and glucose regulation. Learn about the scientific basis for this hormone and whether or not certain natural variables can enhance its levels.

DISCLAIMER: This article’s purpose is to discuss the scientific results of GLP-1. In addition, it provides some information regarding the clinical usage of GLP-1 agonists as anti-diabetic drugs. Consult your Portugal physician regarding your medicine and symptoms.

What exactly is GLP-1?


Glucagon-Like Peptide 1 Portugal is described by researchers as a neuropeptide and an incretin [1].

Neuropeptides are peptides that influence the neural system. Incretins are metabolic hormones that lower blood glucose levels after meals.


GLP-1 is not the sole hormone influencing blood sugar management and insulin production. Numerous other essential enzymes, such as DPP-4, hormones – including glucagon, growth hormone, cortisol, adrenaline, sex hormones, and thyroid hormones – and routes that influence blood sugar and insulin homeostasis.

In addition, blood sugar regulation can be affected by various other variables that vary from each individual, such as blood chemistry, environment, health state, and heredity.

GLP-1 Agonists

Due to its role in insulin and glucose regulation, Glucagon-Like Peptide 1 has garnered a great deal of scientific attention. As a result, a new class of drugs known as GLP-1 agonists was created. Except for semaglutide, these drugs are normally administered through injection [1].

Doctors may give GLP-1 agonists to type 2 diabetics with inadequate blood sugar control who are on oral anti-diabetic medication.

GLP-1 agonists include:

  • Byetta/Bydureon (exenatide)
  • Lyxumia/Adlyxin (lixisenatide)
  • Ozempic (semaglutide injections)
  • Rybelsus (oral semaglutide – the only oral GLP-1 agonist)
  • Tanzeum (albiglutide)
  • Trulicity (dulaglutide)
  • Victoza (liraglutide)

Weight loss and nausea are adverse consequences of GLP-1 agonists [2].

In a few trials, GLP-1 agonists have been linked to asymptomatic pancreatitis and pancreatic cancer; however, this link is currently being investigated [3].

DPP-4 inhibitors

DPP-4 inhibitors are an additional class of anti-diabetic medications. They decrease the activity of the enzyme DPP-4, which inhibits Glucagon-Like Peptide 1 and another incretin termed insulinotropic polypeptide (GIP). GLP-1 and GIP are secreted after meals to lower blood sugar [4].

Consequently, these medications promote glucose homeostasis and GLP-1 activity inside the body.

Inhibitors of DPP-4 include:

  • Sitagliptin
  • Saxagliptin
  • Linagliptin

If you have diabetes, your Portugal physician will explore your pharmaceutical choices in depth, including the possible use of GLP-1 agonists or DPP-4 inhibitors.

GLP-1 Studies and Anticipated Health Effects

Blood Glucose & Diabetes

As previously stated, compounds that operate similarly to GLP agonists, known as GLP-1 agonists, are employed as anti-diabetic drugs.

Glucagon-Like Peptide 1 boosts insulin levels and reduces glucagon levels, resulting in lower blood glucose levels [5].

GLP-1 appears to delay stomach emptying, which reduces glucose spikes and makes it simpler for the body to regulate blood sugar levels immediately following a meal [6].

GLP-1 agonists increase the activity of insulin-producing beta cells in the pancreas of diabetic rats. Scientists believe these medications can restore pancreatic cells, although this has not been demonstrated in humans [7, 8].

When GLP-1 levels are high, cellular research examines whether fat muscle cells also boost glucose absorption [9].

Before discovering Glucagon-Like Peptide 1 agonists, scientists investigated the effects of GLP-1 injections in diabetics [10].

In a 6-week research, GLP-1 injection to type 2 diabetes patients decreased fasting blood glucose and haemoglobin A1c, a marker of long-term sugar management (11).

GLP-1 has a short half-life of approximately 1.5 minutes and is promptly inhibited by the enzyme dipeptidyl peptidase-4 (DPP-4). Therefore, GLP-1 agonists were designed to overcome these challenges and achieve long-term glucose control [10].

Appetite and Weight Management

Certain Portugal researchers suggest that Glucagon-Like Peptide 1 suppresses hunger by acting on specific brain regions. In addition, GLP-1 agonists have the side effect of weight reduction, which patients with type 2 diabetes typically seek. Nonetheless, the results of GLP-1 on weight in adults without diabetes have not been adequately confirmed [1].

GLP-1 appeared to cause satiety in rats that had been fasting. The authors hypothesise that GLP-1 in the hypothalamus suppresses appetite [11].

In one Portugal experiment, chocolate milk was used to entice animals. They hypothesised that GLP-1 decreases the anticipation of a food reward, thereby decreasing hunger and food motivation [12].

We cannot extrapolate animal findings to humans, so it has to be seen whether or not this hormone affects hunger and weight in obese individuals.

Numerous drugs once reported to cause weight loss in animals have been disproved by subsequent clinical studies.

Based on animal studies, leptin was first referred to as a “miracle medicine for obesity.” However, we still do not know precisely what role leptin plays in the human body. Portugal Obesity studies pertaining to GLP-1 may meet a similar fate.

Neurology & Mental Health

According to a study on rats, GLP-1R in the hippocampus improved learning and memory. According to one unverified theory, Glucagon-Like Peptide 1 Portugal could be involved in protecting the brain against seizures and neuronal damage. If confirmed, this would expand our understanding of the gut-brain link [13].

Exenatide, a GLP-1 agonist and anti-diabetic medication, is also being studied for neurodegenerative disorders. Given to 45 Parkinson’s disease patients, exenatide appeared to alleviate motor and cognitive symptoms compared to the placebo. However, consequences included weight loss and nausea. Large-scale research is needed [2].

Some researchers have suggested that the possibly preventive qualities of GLP-1 agonists should also be investigated in Alzheimer’s disease [14].

GLP-1 tends to alleviate mood and anxiety in laboratory animals. It is theorised that this stimulates the wakefulness-inducing hormone orexin. However, the effect of GLP-1 on human mood and alertness is uncertain [15].

Other Research Areas

Scientists are exploring whether Glucagon-Like Peptide 1 promotes cardiovascular health [9], dilates blood arteries (vasodilation) [9], and enhances salt excretion [9].

GLP-1 Portugal may also participate in several potentially harmful processes. For example, GLP-1 appears to exacerbate the stress response and anxiety in certain animal studies [17, 16].

Another animal experiment revealed that GLP-1 and GLP-1R might be responsible for elevated blood pressure and heart rate in response to stress. According to the authors, this may be related to maintaining energy balance [18].
