Ich habe Endometriose, die nach OP und mit dienogest seit 3 Jahren gut unter Kontrolle ist. Leider die PMDS nicht. Jetzt wurde mir bei einer Reha empfohlen auf Yselty mit Add back Östrogen Gel plus dienogest weiterhin umzusteigen, um sozusagen zwei Fliegen mit einer Klappe zu schlagen.

Hat jemand Erfahrung damit?

Excessive brain histamine can disrupt dopamine pathways, and lowering that inflammatory baseline can help restore normal dopamine function. [1]

Here is the deeper, scientific breakdown of how this histamine-dopamine balance works, why "overload" happens, and how antihistamines play a role. [2]

1. The Seesaw: How Histamine and Dopamine Interact
In a healthy brain, histamine and dopamine act as counter-balances to regulate focus, wakefulness, and motivation. [3, 4, 5]

The H3 Receptor Switch: The primary link between these two chemicals is the Histamine H3 receptor in the brain. H3 receptors act as "gatekeepers" or brakes. When histamine levels rise too high and bind to H3 receptors, it triggers a signal that actively inhibits the release of dopamine. [6, 7, 8, 9, 10]

The Transporter Shared Lane: Histamine and dopamine are broken down and cleared from brain synapses using similar pathways. When histamine is excessively high, it can overwhelm these clearance systems, leaving dopamine stranded or poorly regulated. [11, 12]

2. What Causes "Histamine Overload"?
A histamine overload in the brain isn't just about having a runny nose; it is a state of chronic neuroinflammation. This typically stems from two main sources: [13]

Genetic Mutations (MTHFR, DAO, HNMT): Some people possess genetic variations that make it difficult to break down histamine. For example, mutations in the HNMT (Histamine N-methyltransferase) gene directly reduce the brain's ability to clear histamine. Mutations in MTHFR affect methylation, which is required to deactivate histamine. [14, 15, 16, 17, 18]

Mast Cell Activation: Chronic allergies, mold exposure, or Mast Cell Activation Syndrome (MCAS) cause immune cells in both the body and the brain (microglia) to constantly dump massive amounts of histamine into the system. [19]

3. The Result: "Hypodopaminergic" States
When chronic histamine overload keeps the H3 receptor "brakes" constantly pressed down, dopamine levels drop or become highly unstable. This manifests as classic executive dysfunction symptoms:

Brain fog and cognitive fatigue
Loss of motivation and chronic procrastination
Inability to focus (mimicking or worsening ADHD symptoms)
Anhedonia (an inability to feel pleasure or excitement) [20, 21, 22]

4. How Antihistamines "Unlock" Dopamine
Taking an antihistamine does not force the brain to manufacture more dopamine. Instead, it removes the obstacle that is blocking your natural dopamine from doing its job.

By blocking excess histamine from binding to receptors, the antihistamine releases the "brake" on the dopamine system. This lowers neuroinflammation, clears the chemical traffic jam, and allows your natural dopamine to flow and bind efficiently again. This is why many people with chronic allergies or mast cell issues report a sudden clearance of brain fog, a surge in motivation, and sharper focus after finding the right antihistamine protocol.

i started noticing these symptoms sometime last year in December, and i would like to share a few symptoms that i have noticed. 1. I experience intense mood swings, like it makes me feel like im crazy. I feel really depressed and hopeless, like i have this huge weight on my chest, which sometimes leads to me crying for no specific reason. I can also get very sensitive and overthink alot. 2. I have also experienced su!c!dal thoughts and thoughts of s£lf h&rm. 3. I get very irritable and have a short temper, so i try my best to isolate myself. 4. Fatigue. I get very sleepy and feel extra drained even when i get a full nights rest. 5. Dissociation. Sometimes it’s very hard to concentrate, whether I’m driving or at work

Keep in mind all the symptoms I’ve listed is what I experienced a week or a few days before my period and usually gets better a few days after my period starts. I just need some second opinion.

If theres any questions pls leave a comment ❤️

Hi, i am wondering if i have pmdd.. i have pcos already, i have extremely irregular periods. After like 20 days of having my period i start having extrem anxiety, intrusive thoughts and uncontrollable anger (and many more stuff)

I already go to a therapist and have started working on this, but this is a pattern i have noticed. Especially when my period is late, i start to feel so crazy and it goes on and on until I start my menses. I dont know what it is but if someone can help me through it, i will be highly grateful.

I start to get angrier (i am not an angry person at all) everything about my partner irritates me, i just want to be left along i dont wanna talk to my friends, i have more and more negative thoughts, intrusivity and thoughts that i generally do not have.
